The speed of a wave in medium is `760 ms^(-1)`. If 3600 waves cross a point in the medium in 2 minutes, then the wavelength of the wave is :

A

13.8 m

B

25.3 m

C

41.5 m

D

57.2 m

Text Solution

Verified by Experts

The correct Answer is:
B
Frequency `n = (3600)/(120) = 30` Hz , Wavelength `lambda = (v)/(n) = (760)/(30) = 25.3` m
