Question

2 tuning forks a and b vibrate with frequencies in ratio 2:7 and their wavelengths in ratio 3:4 respectively
find the tuning fork producing greater velocity of sound​

Answer 1

B is the answer...

Explanation:

We know that, v=uλ, where v is the speed of sound wave, u is the frequency.

Now

Let, v

A

and v

B

are the speed of tuning fork A and B.

then, v A /v B =uA /u B ∗λ A /λ B

We get, v A /v B =6/28

Therefor, we get v B >v A

Hence, Velocity of Sound is greater in Fork B
