The hero of physics...sir Atif Ahmad🥳🥳👌 love u sir....♥️♥️

[@laibaabbas4452]

In our textbook, topic closed organ pipe there is no 2nd harmonic there is 3rd harmonic and fifth harmonic

[@mariya07]

MashAllah wonderful explanation. Sir, you're so hardworking and patient. You make sure every time that each and every concept is cleared by constant revision. 🙂

[@salmanrauf4669]

Sir confusion ye hai ky loud sound constructive interference k wajah se sunayi de raha hai ya resonance ki wajah se ??????

yes sir, kindly guide plz!

Sir Ahmed AAP se sawak Tha ke AAP ny to is topic mn 1 2 or 3 harmonic explain Kiya magar hamary kpk Ki book mn yhi topics 1 3 5 harmonic Likha Howa Hai is ka Kya mtlb book mn galat Likha Howa Hai

[@Ahmed07O71]

mera khayal ha ke book mn pie/4 ko one harmoic lia ha . 2 resonace mn 3pie/4 length ha so 3 harmonic hoga . Ye shaid logic ho

Dear sir, after resonance the loudness of sound is increased( which means extra energy is produced)..... Is it not against the law of conservation of energy?

[@officialroast8053]

Nice👍

[@tabindaarif324]

👍👍💓💓

[@MmAaZzzz]

sir, can you give the proper written answer that why sound i.e. longitudinal in nature but shown as transverse wave in diagram

[@atifahmadofficial]

No no no... it not transverse wave, it is actually the graph of amplitude of vibration of air particles at particular point...

[@MmAaZzzz]

@@atifahmadofficial Noted+Thank you

[@zuneraanjum7362]

If amplitude will be zero than its displacement will be what?

[@fluxpubgmobile6904]

Obviously 0

[@Mehru5544]

Amplutude is never zero because amplitude is the longest displacement from mean pos thus only displacement can be zero

Last lecture me 2nd harmonic ki value f2 = 2f1 Lamda ati thi or isme 2nd harmonic ki value f2=3f1 lamda arahi jo ke 3rd harmonic ki value hai … Same goes for 3rd harmonic , in previous lecture 3rd harmonic was f3=3f1 lamda and here its f3=5f1 lamda which is value for 5th harmonic … I’m getting very confuse, Sir can you please explain it ?

[@ahmadkamal6134]

It is because the second harmonic would be at the second antinode which is not possible at the close end so we need a node at the end of closed pipe therefore we discuss 3rd harmonic immediately after the first one.

[@noorzahra5150]

We dont need a node, as node gives no sound. There is minimum vibration at node. Rather we need an antinode here. Since 2nd harmonic will give a node ( a full loop = lambda/2 ) we ignore that harmonic and take the 3rd harmonic instead. Third harmonic will give us a full loop and a half loop. (3×lambda/4) Therefore we will have antinode at open end and sound will be produced. Similarly 4th harmonic will produce 2 full loops and we will get node (no sound) at open end so 5th will be taken instead. (Producing 2 loops and a half)

[@zohakhan714]

@@ahmadkamal6134 Thank you Ahmad ! But the thing which confused me is that what would we call f2=3f1 lamda ? 2nd harmonic or 3rd harmonic? Or the name doesn’t matter? because in book it is called 3rd harmonic and here Sir named it 2nd harmonic.
