A sound wave whose frequency is 5000 Hz ...

A sound wave whose frequency is 5000 Hz travels in air and then hits the water surface. The ratio of its wavelength in water and air is

A

`4.30`

B

`0.23`

C

`5.30`

D

`1.23`

Text Solution

Verified by Experts

The correct Answer is:
A
`f = 5000 Hz , V_(a) = 343 ms^(-1) , V_(w) = 1480 ms^(-1)`
Ratio of wavelength `(lamda_(a)) /( lamda_w) = (V_(w))/(f) xx (f) /(V_(n )) = ( 1480 )/( 343) = 4.31`
