The speed of a wave in a certain medium ...

The speed of a wave in a certain medium is `960 m//s`. If 3600 waves pass over a certain point of the medium in 1 min, the wavelength is

A

2 m

B

8 m

C

4 m

D

16 m

Text Solution

Verified by Experts

The correct Answer is:
D
As `v = 960 m//s, v = (3600)/(60) = 60 Hz ,`
`lamda = (v)/(v) = (960 m//s)/(60 Hz) = 16 m`.
