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

4.3

B

0.23

C

5.3

D

1.23

Text Solution

Verified by Experts

The correct Answer is:
A
Frequency of sound , f = 5000 Hz
` v_a = 343 ms^(-1)`
v_w = 1480ms^(-1)`
The ratio of wavelength `(lamda_a)/(lamda_w) = (v_w)/(v_a) = 1480/343 = 4.31 `
