Sound Medium | Propagation of Sound | Why does sound travels faster in solids?
HTML-код
- Опубликовано: 8 сен 2024
- Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids.
The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster the sound travels in a medium. The mathematical relationship is speed = (elasticity/density).
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)! But, this is only for the majority of solids. The speed of sound in all solids is not faster than in all liquids.

thank you! if im honest theres an ocean of science videos speaking english with strong accents that i find hard to understand or even listen to for a while. but wish i could. videos like yours show me its not the accent its the presentation and communication skills beyond just pronunciation :D
That's sounds Great that you are learning easily!

By the way nice explanation ❤
Happy to hear that!!
Reminds me of my school life
I didn't paid much attention though
Thanku so much for explaining in such easy manner😍
What about density because I read somewhere that higher density means sound wave will travel slower?
Thank You for this Video😎👍
This video is underrated

SIR I HAVE A DOUBT PLZ REPLY ME AND CLEAR IT FOR WAVE PROPOGATION ELASTICITY OF MEDIUM IS NECESSARY...BUT WE KNOW THERE IS NO ELASTICITY IN FLUIDS SO WHY LONGITUDINAL WAVE TRAVEL IN FLUIDS...

Sir, I had a doubt....
Molecules in solid are dense.
You said that sound travels faster in solids.
Now, in the textbook its given that velocity of sound is inversely proportional to density. So, if density is increased 4 times, then velocity reduces to half.
So, in solids the Velocity of sound should be less then as per this.
Please solve my doubt🙏

Thanks for the video. I find it immensely annoying that scientists often use common terms with their opposite of their intended meanings. Everyone is brought up with the understanding that "elastic" means stretchable, yet, in physics, it is the exact opposite. LoL It is so frustrating.

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.
The speed of sound in a medium (like air) is indeed constant at a given temperature and pressure (approximately 344 m/s in dry air at 20°C). However, the formula \( \text{speed of sound} = \text{frequency} \times \text{wavelength} \) is used to relate the frequency and wavelength of sound waves. Different frequencies produce sound waves with different wavelengths, despite traveling at the same speed. This formula helps us understand how sound characteristics (frequency and wavelength) relate to each other, not the speed itself.

4:30 Then why in gases velocity of doing if inversely proportional to root of density?
elasticity is the resistance, if the particles resists to oscillate, it means more elastic, you cannot relate speed of oscillation of a particle to speed of wave propagation (medium).

with refraction of sound waves when a sound wave goes from a less dense object to a more dense object why does it speed up and not slown down like a normal wave would

Do the speed of the sound also depend on density of a medium?
If yes, then how?
Because if a material has high density it will automatically have higher elasticity i.e its ability to retain its shape since more no. Particles in a smaller area will provide high resistance to deformities as compared to lesser no. Of particles in that same given area. Hope this helps
Then, sound to jyada solid me aani chaiye....
But Velocity of sound decrease with increase in Density !,Then Solids have more density than liquid and gas then how Speed of sounds decrease with increse in density ?

sir please answer me this question.
if sound can move in solid medium then why we can not hear sound when some one speak in a closed room etc..
I think so,it's because inside the room when you speak the vibrations are first carried out by the air only.
And by the time the vibrations reach the wall,energy dissipates means the energy used by your larynx to vibrate air gets used up.
And maybe it's about on what surface vibrations is made.
Like,
When you speak through a solid like a door
Or
When you create vibrations by tapping the door.
In first case,the vibrations is first carried out by air then travels through the door
In second case, the vibrations occur on the surface of the door.
I am still not sure,that's the correct reasoning
I may be wrong.
Good question!
@@user-zo2sj5is4k yeah thank you..then i got the answer your answer is absolutly right .
when we speak inside the room , air vibrate when it strike the door wall etc it reflected back and sound in solid mean to vibrate the solid particale
