1:10:53 if we increase more sound music then that music leads to noice pollution??in music only constant frequency and amplitude exist thriughout the song??noice contains different frequency and amplitude??

[@devisravani7277]

High pitch voice is clarity compared to low pitch?

[@user-kz5hw7if5n]

Sir your explanation is so simple and very helpful to the students best explanation of physics subject fab

[@MridulAm-xv7uj]

This guy saved ma whole exam

[@Sunnylucythefriends]

Thank you so much sir ☺️

[@jhansikumarjkrk8693]

Very useful sir .thank you sir

[@sirishayalla1075]

Sir sound will not travel in solid or liquid or gas or vacuum

[@raziyakareem7432]

Solid

[@sudaroisudaroli8956]

Sound can not travel in vacuum

[@sudaroisudaroli8956]

Sound can also travel in liquid and gas and solid

[@sivasatyanarayanachaganti8444]

Iknow this sound lesson before only on 8

[@sivasatyanarayanachaganti8444]

Sorry😊

[@santhiprabha9542]

Thank you guru

[@satyasree4735]

Nice explanation

[@sarojinimalleda6850]

Thank you so much sir it helpfull for my novodaya exam

[@devisravani7277]

Sir plzz give any example for the formula at 1:02:42 regarding loudness and amplitude

[@devisravani7277]

Aplitude formula?

[@devisravani7277]

For 10db loudness how much or how many frenquency is being generated from the breath Any relation ship is there between Amplitude and frequency??

[@jaatsaab292]

Good

[@srinivasan-bl6ol]

Good teaching sir

[@sasikumarmarkandan8677]

Thank you so much

[@sandeshsanju777]

Thank you sir

[@devisravani7277]

Frequency is directly proportion to amplitude?if yes then at which case this condition is applicable?

[@sirishayalla1075]

Aa good ok

[@devisravani7277]

Trees cant propagate sound furthur?

[@aitharajuswathi9419]

🎉

[@aitharajuswathi9419]

Superb 😊

[@mandaviprabhudessai6459]

sir, very nicely explained.

[@veenaprabhakar9089]

i love ur gyatt

[@nithishanithisha9794]

Very nice sir 😊

[@devisravani7277]

Sir in 17:08 when we hit the vessel with spoon slowly it gives sound but we cant able to see the movement of vessel .I mean you said that body moves or vibrates(which we can see the moves of the body) my doubt is we are hiting the vessel(body) with spoon slowly without any movement of the vessel vessel is producing sound how sir? In your perspective vessel(body) should have to move orvibrate then only it gives sound but my case I not able to see the movements of vessel when iam hitting slowly with my spoon Plzzz clarity my doubt sir

[@devisravani7277]

Means Iron kind of bodies when we hit hardly also dont move easity but produce sounds Thats why i got doubt I my school bell rangs at my lunch break i observed the person who rung the bell he just hit the bell hardly the Iron body kept vertical to the top it moves and gives sound but in my home Iron pan which kept horizontally on the wall and I hit that pan but I didnot observe movement or vibration of the pan eventhough i hit hardly but giving more sound that is giving sound pollution What is the reason behind this sir plzz clarify sir

[@devisravani7277]

Sir which object should vibrate the object which we are using to hit the pan or the object which we are hitting .which object should vibrate (pan or spoon ) to get the sound from pan

[@devisravani7277]

Frequency means the vibrated sound how long it will give sound and Aplitutude means how much sound we get from the place were the sound is being generated??this analogy right or wrong tell anyone

[@shaikhaseena3946]

What's meaning by dynamics

[@filmymoji123]

Moving

[@Lucy_telaila_.]

It really helped me....before it was hard for me to understand, but now it seems like its a piece of cake to me 😅😊

[@learngrow4839]

U r amazing

[@banothrajitha5807]

Sir your class is superb 👍👌

[@devisravani7277]

Human cant get sound after 20000 Hz or human get effect his ears when hearing 20000Hz plzz give reply sir

[@filmymoji123]

No

[@ravinasinaravi964]

Sir your explanation super I understand clearly without any doubt

[@santoshdb4901]

Good information sir 🎉

[@guggillahemasai4177]

Very nice explanation sir when my teacher I Don't understand but now I understanding the chapter 😊😊

[@gandhodiharikumar110]

Sir 52:44 the electric signals going to nervous is equal to the electricity produced to the home current appliences??

[@veenaprabhakar9089]

date me

[@sudharshanyadav661]

Sir why get blood from ears after listening noise

[@sahanaa8590]

Thanks gunda
