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

May Allah grant you jannah inshallah!!

Mash Allah wonderful explained . Think sir G

thank u sir for your outstanding explanation

Really really really thank you I hate these topics but now I understood these just because of you... 💕💕💕

Thank you sir and god bless you

Thanks sir...❤

Time saving ❤ lecture

So can we say that after the fundamental frequency the pitch of sound will increase for every overtone?

outstanding👌💚

Thank you so much sir I was stuck here

Thank you sir😊

Great lecture Sir

Excellent💯👍

Thanks Sir 💫

sir at 17:13 yhan pe apne btaya ke max amp pe awaaz max sunai de gi aur constructive interfenrence hogi, but yhan pe to distructive interference hini chahe jese crust trugh ke upre ha

v good explanation Sir

Nice

Long live sir atif.......Allah apko hamesha happy rakhain sir😊😊😊😊

Sir please also upload or make notes on lectures, thank you sir 😊😊

Sir you dont know how much i am thnkful to you 😊❤

sir aap legend hyn kasam sy

What about reflection of longitudinal waves from denser and rarer medium

The best thing about you is that you dont think that no matter how much I consume time to draw these diagram and deliever lecture but my students should not suffer ❤❤❤love from kp

Finally ended up i found a great teacher❤❤❤

Assalamualaikum sir ap yahan length ko constant rakte hain but udhar node antinodes tab hi change horahe hain jab ham colom ka length change karte hain...but ap ne calculation karte waqt length ko same hi lya hai every case me

sir KPK book mein jis se apne ye lecture bunaya hai us mein f2=3f1 ko 3rd harmonic likha hua aur f3=5f1 mein 5th harmonic, kia ye mistake hai?

thnx for the time steps option in description, that is very helpful

Sir great about the concept you gave about the longitudinal waves.

Wow ❤❤❤❤❤

Sir u are Sindhi?

I must say best physics tutor 🤩 Thankyou

Salam, in transverse wave f2=2f1 , but in longitudinal wave f2=3f1. Am I right ?

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

Sirr kya ap sindh ka bu stah parhaty hai plz reply

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?

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

Жыл бұрын

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

Жыл бұрын

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)
