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

13.8m

B

41.5m

C

25.3m

D

57.2m

Text Solution

Verified by Experts

The correct Answer is:
B, C
Number of waves crossing a point per second.
`n=(3600)/(2xx60)=30`
`lamda=(v)/(n)=(760)/(30)=25.3m`
