Hello.. i dont know why i am confusing.., my question is 1.what is the relation between the amplitude and peak to peak in a waveform? 2.what is the relation between frequency and time? Please answer these.. I am still confusing after watched your videos also..
tq u master tr nabamitha mam it was really helpful for my exam as i didnot listen to my class properly and didnt understand de consept properly and after watching the video i understood it very well...
Mam you had explained so easily and your teaching way is also so good,but a doubt is raising that what is amplitude, mam can you plz tell it in another way plz,plz.
equilibrium is the position of air molecules when it is not disturbed by vibrations or other things so it is the undisturbed position of air molecules.
Audible range of sound that human beings can hear is 20Hz to 20000Hz. And the inaudible range of sound is below 20Hz and above 20000Hz. AM I CORRECT????🤔🤔🤔
(summary of lesson 1 and 2 of nabita ma'ams videos) -Vibration is the faster movement of a body which could or could not produce sound, pretty close to oscilation. -In a flute we do not a have a sensation of a vibration, we have a air column, when air is passed through the air column, it collides the column boundaries, and if noticed the musician playing the flute places his/her hand on to the holes. Therefore creating sound! -Another example of this is and old ancient form of producing sound, filling few bowls of water and while using some sticks you can create ripples in the water (the water in each bowl should be different for the difference in the sounds produced) These ripples are the result of vibration or the impact of the stick hitting the bowls. -By this we also conclude that souns create vibration, and vibrations creates sound! -In humans we can take an anology of a flute as well, the wind pipe acts as the air column and the sound is produced through vocal chors which also produce vibrations. the vibration here is produced when we exhale while talking, the air molecules hit eachother creating vibrations and therefore sound! (Fun fact of my own: You can't talk while inhaling!) - Sound is energy, let's take an instance, i am talking about something and you are able to hear it. This is because, while talking i transfer the energy produced from my vocal chords to the air molecules present in air. - These molecules then start moving passing the energy (sound) from one molecule to another and therefore letting the sound travel. - The origination of the sound is the place where the molecules which have the energy colide with eachother, this colision pushes the molicules further away, and therefore coliding with the molecules present in front. - This is how contraction and relaxation takes place. - The sound is also enabled too travel in solids and liquids.
Man, I have a doubt. Why amplitude does not affect the time period of the longitudinal wave? If I take the example of a sound wave, then amplitude means the maximum distance covered by the air particle to either left or right side to it from the equilibrium, right mam? So, If amplitude is higher, the particle has to cover that much distance to its right, then to the mean position, then to the left, and then back to the mean position to complete one oscillation, if my understanding is right. Then won't the particle take more time to complete one oscillation? I am really confused 🙁
actually low frequency mai particles bohot slow move kar rahe hai ....that's why they are taking more time and in high frequency particles are moving fast ....that's why they are taking less time... I HOPE YOU UNDERSTAND ..🤗
for example . if i am playing a music on the speaker through Bluetooth through my phone the phone will convert the sound frequency into electrical signals or radio signals and the speaker will receive it and decode the signal again into sound frequency
No sound cannot travel in space because sound needs a medium like solid, liquid and gas but in space there is no medium. So sound cannot be heard in space
@@AR1DH18A beta in bell electric energy is used to hit bell and vibration is produced... In case of pen sound is produced due to change in pressure of air by air blown by your mouth.
The loudness of sound depends upon ampitude.When the amplitude is very large, the sound produced is loud.When the amplitude is small,the sound produced is feeble..
Ma'am my name is harsh raj . Very very good morning to you ma'am .Ma'am, please put a chapter on "Friction" . Ma'am I need the knowledge of this chapter.
mam please again tell that what is amplitude and frequency i really didnt understand that and i m having my h.f. tomorow for science and i m here cause u r my favourite teacher

So many people are confused and hope to get there doubts cleared by you in this comment section.
frequency is the measurement of the number of times that a repeated event occurs per unit of time.
in simple words, it is how many waves pass a point every second

Thanks for your help...
@Nitigya Nandan Bhagawati yes bro
Frequency = how many times did oscillation takes place
Mam urr explanation is very best.. Now,,, I'm understand all topics..

Thanku mam.Your teaching style is too good mam.
Hello..
i dont know why i am confusing.., my question is 1.what is the relation between the amplitude and peak to peak in a waveform?
2.what is the relation between frequency and time?
Please answer these.. I am still confusing after watched your videos also..
I too , have the same doubt
The more the frequency the less is the time period
Thank you for teaching well in this lockdown

Very easily understand mam you are the best
Mam you had explained so easily and your teaching way is also so good,but a doubt is raising that what is amplitude, mam can you plz tell it in another way plz,plz.
Urs explination is superbb tq so much mam
Audible range of sound that human beings can hear is 20hertz -20,000 hertz
Yes
Nabamita Ma'am teaches wow! But Still i have a doubt😅
What is And where is Equilibrium in sound or Amplitude
equilibrium is the position of air molecules when it is not disturbed by vibrations or other things so it is the undisturbed position of air molecules.
@@agmaioshorts.4257 Ok thanks
Mam ur teaching is very very amazing

Thanks
Mam....😄😄😄

you should ask this question in her telegram, she'll reply you, I hope so.

I HOPE YOU UNDERSTAND ..🤗
because the amplitude is the movement perpendicular to the wave motion
it does not affect the limit of frequency because it is the vertical axis
@@hmrdarkhawk8543 But as far as a longitudinal wave is concerned, the direction of wave is same as the direction of amplitude.
Mam it's not contraction and rarefaction it's compression and rarefaction
Yes right
The maximum displacement of an oscillating body from its central position is called amplitude (ob or oa)
