The distance between two consecutive cre...

The distance between two consecutive crests in a wave train produced in a string is `5 cm`. If two complete waves pass through a point per second, the speed of the wave is :

A

`10 cm//s`

B

`2.5 cm//s`

C

`5 cm//s`

D

`15 m//s`

Text Solution

Verified by Experts

The correct Answer is:

A

As `lamda = 5 cm, v = 2, v = v lamda = (2 xx 5) cm//s = 10 cm//s`.
