17 meters ke pass Sound echo toh nahin karega lekin reverb toh karega na? Kyunki Rock ek achha material hai jo echo produce karta hai.

Umm excuse me sir, could you please tell me how to concentrate. I love physics and maths from childhood. I also love reading variety of books on cosmology. But now a days i have lost my concentration so much that a single clap sound can disturb me from my books. Could you please help me sir. Thank You

i think it is all because you have lost all your interest from those subjects and you are reading them for only knowledge you should read them for fun and should apply whatever you read . i too resolved my problem with this method and i too love reading them but instead of just reading i try to apply them in my daily life so that i dont lose my interest

I have a doubt sir .... At 22°c the speed of sound is 344 m/s .... So if we calculate then the minimum distance will be 17.2 meters that is given in our textbook .... But my teacher says that if the distance between source of sound and obstacle is more than 17.2 meters then we cannot hear the echo .... I told her that if the distance is more than 17.2 meters then also we can hear echol but she said that it is wrong .... We can only hear echo if the distance is exactly 17.2 meters .... Please tell me how can I explain her
@bhatadha9255Ай бұрын
She's dumb or what? Simply say that's a minimum criteria not the maximum
@utkarshgamer7205Ай бұрын
To hear the sound distinctly (clearly) then the minimum distance between reflecting surface in air should be at a minimum distance of approximately 17metere

Kyoki wahan pr koi aisa saman nhi hota jo aap ke sound ko absorb kre aur isliye aapki awaj aapko reflect ho ke sunai pdti h. But wo eco nhi reverbation(गूंजना) hai. Eco tb hogi jb room 17m lamba ho
