@@mkhanstar9552 it has to do with the mediumds elastic properties. These properties usually increase with higher density, but the increase in the elastic properties is much greater than the increase in density, so the total sum equals a bigger velocity

That point in the video is wrong, density decreases as temperature increases-accepted But we cannot State that speed of sound depends only upon the density, (inversely proportional to density) We have to consider the temperature along with it, if we keep the temperature constant, the density is directly proportional to the speed of sound :)

It depends on the elasticity and the rigidity of matter . the elasticity of the medium depend on the temperature , though . but while keeping the temperature constant . speed of sound depends of the √Elasticity/√density.

guys don't compare the factor density and humidity with temperature.... for temp key factor is kinetic energy other factors affect that very least... so elasticity and k.E overcome that ....and besides that density and temperature have different relation and even all these have different variation with water gas and solids see that in class 11th physics

What about solids being more dense than air? Then, increasing the density would increase the velocity of sound. So, what's the catch? Is acoustic theory incorrect?

Good question ! The thing is, he didn't talk about an important factor that affects the speed of sound between fluids and solids. He did not mention the Elasticity of the material! Sound in solids, because they are very dense, travels faster than in a denser gas, because in solids the elasticity of the medium is much greater than in gases. In gases, another factor also comes into play that makes it lose speed much more than in solids, compressibility. There is no compressibility in solids and liquids and therefore the elasticity is much greater in these media, that even a denser Air, due to its variable compressibility, delays the shock and the faster advance of the molecules of that Ar (lower propagation velocity)... Because of this compressibility in gases, affected by relative temperature, sound takes much longer to travel in this medium. That's why sound travels much faster in solids than in denser gas.

Hello sir, Your explanation is really fascinating but I have a doubt. Could you please clear it out? You said that if tempreture increases, density decreases, till here I understood. But how decreasing density increases the speed of the sound in air... Hope you would reply and make it clear... ☺️

If speed of sound is constant (344m/s) then why do we calculate speed of sound for different wavelengths, with the formula ... speed of sound = frequency x wavelength. Because there are numericals given in kid's textbook to find out speed of sound with the given frequency and wavelength. Some websites on Google says speed of sound is uniform (344 m/s) and does not depend on frequency or wavelength, when the opposite is clearly given in the formula. Please explain.

correction:- density of humid air is less as compared to density of dry air as density is inversely proportional to velocity of sound therefore speed of sound increase if humidity increase!!!!

ok sir but you mean to say if density of medium increases the speed of sound decreases but if we compare the density of water and air then according to you in air the speed of sound will be fast but in really it doesn't happend
You are actually right . but speed of sound doesn't depend on the density , but it depends on the elasticity and the rigidity of the matter . speed of sound is directly proportional to the elasticity of the medium , air has more elasticity . thus speed of sound is faster in air . if the solids are elastic speed of sound in them would be the fastest .

Formula for velocity of sound is √(Elasticity/Density) given by Newton. So for solids if Density is double then liquids or gases, Elasticity is almost four times. Hence Elasticity is dominating factor here hence overall velocity increases according to the formula.

Not understand well the concept of density As temp. Increases so density decreases and you tell velocity of sound increases ,, but before u tell that due to more no. Of molecules speed of sound travels faster but due to decrease in density moleculer distance is greater than previous so if molecules are at more distance than speed of sound has to be ddecrease.
I cant understand this. You just said that when there is humidity there is more number of molecules so speed of sound increases But in the same way when density is more the molecule are more closed so speed should increase and at low density speed should decrease ? Isn't it ?

Ok
@@mkhanstar9552 dont it's a scam
@@mkhanstar9552 it has to do with the mediumds elastic properties. These properties usually increase with higher density, but the increase in the elastic properties is much greater than the increase in density, so the total sum equals a bigger velocity
Sir please clarify this doubt
Thanks for such a great explaination 😀😊

Sir but it travels faster in solid than in liquid and gas..
how density is inversely proportional...
plz explain
Same confusion after seeing the video
that's my question too
and its answere will never ever come
It's only for the case of air
That point in the video is wrong, density decreases as temperature increases-accepted
But we cannot State that speed of sound depends only upon the density, (inversely proportional to density)
We have to consider the temperature along with it, if we keep the temperature constant, the density is directly proportional to the speed of sound :)

If Volume Increases, Density Decreases but Collisions and movements b/w particles decreases so speed should be decreased...

No on heating collision between particles increases as there kinetic energy increases as a result their speed also increases .
if no. of molecules increases then speed sound of will be slow...plz check this fact or if im wrong plz correct me

Then vol.will increase

It depends on the elasticity and the rigidity of matter . the elasticity of the medium depend on the temperature , though . but while keeping the temperature constant . speed of sound depends of the √Elasticity/√density.

guys don't compare the factor density and humidity with temperature.... for temp key factor is kinetic energy other factors affect that very least... so elasticity and k.E overcome that ....and besides that density and temperature have different relation and even all these have different variation with water gas and solids see that in class 11th physics
It is really a great explanation it is wanted that every school teacher should teach like this

Confusing on den sity as solid liquid
What about solids being more dense than air? Then, increasing the density would increase the velocity of sound. So, what's the catch? Is acoustic theory incorrect?

Good question ! The thing is, he didn't talk about an important factor that affects the speed of sound between fluids and solids. He did not mention the Elasticity of the material! Sound in solids, because they are very dense, travels faster than in a denser gas, because in solids the elasticity of the medium is much greater than in gases. In gases, another factor also comes into play that makes it lose speed much more than in solids, compressibility. There is no compressibility in solids and liquids and therefore the elasticity is much greater in these media, that even a denser Air, due to its variable compressibility, delays the shock and the faster advance of the molecules of that Ar (lower propagation velocity)... Because of this compressibility in gases, affected by relative temperature, sound takes much longer to travel in this medium. That's why sound travels much faster in solids than in denser gas.
Water vapor replace air the air molecules and density of air decrease thus the speed of sound increased

Hello sir,
Your explanation is really fascinating but I have a doubt. Could you please clear it out?
You said that if tempreture increases, density decreases, till here I understood. But how decreasing density increases the speed of the sound in air...
Hope you would reply and make it clear... ☺️

dhoka
If speed of sound is constant (344m/s) then why do we calculate speed of sound for different wavelengths, with the formula ... speed of sound = frequency x wavelength. Because there are numericals given in kid's textbook to find out speed of sound with the given frequency and wavelength. Some websites on Google says speed of sound is uniform (344 m/s) and does not depend on frequency or wavelength, when the opposite is clearly given in the formula. Please explain.

correction:- density of humid air is less as compared to density of dry air
as density is inversely proportional to velocity of sound therefore speed of sound increase if humidity increase!!!!

u said that solids have molecules compactly arranged mean high density so high speed but after some time u r saying that density is inversely proportional. sound

If density is indirectly proportion to speed of sound,then why speed of sound is more in solids than liquids or gases?????

Good question ! The thing is, he didn't talk about an important factor that affects the speed of sound between fluids and solids. He did not mention the Elasticity of the material! Sound in solids, because they are very dense, travels faster than in a denser gas, because in solids the elasticity of the medium is much greater than in gases. In gases, another factor also comes into play that makes it lose speed much more than in solids, compressibility. There is no compressibility in solids and liquids and therefore the elasticity is much greater in these media, that even a denser Air, due to its variable compressibility, delays the shock and the faster advance of the molecules of that Ar (lower propagation velocity)... Because of this compressibility in gases, affected by relative temperature, sound takes much longer to travel in this medium. That's why sound travels much faster in solids than in denser gas.
Explanation is too good

Some thing is wrong .....increase in density leads to increase in pressure.....therefore P/rho remains constant and no effect of velocity
Confusion high temperature's kinetic energy may be infaver but low density can not be in speed of s

ok sir but you mean to say if density of medium increases the speed of sound decreases but if we compare the density of water and air then according to you in air the speed of sound will be fast but in really it doesn't happend
You are actually right . but speed of sound doesn't depend on the density , but it depends on the elasticity and the rigidity of the matter . speed of sound is directly proportional to the elasticity of the medium , air has more elasticity . thus speed of sound is faster in air . if the solids are elastic speed of sound in them would be the fastest .

U said increase in density then sound velocity decreases the what about solid ...because solid has high speed of sound comparetively liquied and gas..why?
The molecule are closed packed in solid..so vibration can esily transfer..is this right or wrong

If sound and wind are in same direction than the speed sound is greater how? For same direction mathematical it will b like that total speed of sound = speed of sound +wind speed so according to this we can't hear a clear sound

Formula for velocity of sound is √(Elasticity/Density) given by Newton.
So for solids if Density is double then liquids or gases, Elasticity is almost four times. Hence Elasticity is dominating factor here hence overall velocity increases according to the formula.
that's lil Nas x so i want aaa someone to love me that's what i want !!!!! 😗

Not understand well the concept of density
As temp. Increases so density decreases and you tell velocity of sound increases ,, but before u tell that due to more no. Of molecules speed of sound travels faster but due to decrease in density moleculer distance is greater than previous so if molecules are at more distance than speed of sound has to be ddecrease.
I cant understand this.
You just said that when there is humidity there is more number of molecules so speed of sound increases
But in the same way when density is more the molecule are more closed so speed should increase and at low density speed should decrease ?
Isn't it ?

But sir the sound go long distance in night whereas the tempreture is low than the day
due to refraction
and second thing in night there is more temp cause earth become hot at day but in night it reduces its temp so that temperature goes into air and make the area more hot
what about elasticity?
Stress / strain
F/a ÷ increased length / original length but the temperature is constant in normal conditions.
Speed
