A transverse wave along a stretched stri...

A transverse wave along a stretched string has a speed of 30 m/s and a frequency of 250 Hz. Then the phase difference between two points on the string 10 cm apart at the same instant is

A

0

B

`pi//2` rad

C

`5pi//3`

D

`8pi//3`

Text Solution

Verified by Experts

The correct Answer is:
C
`delta = (2pi x)/(lamda)`
`= (2pi xx 0.1)/(v) = (2pi xx 0.1 xx 250)/(30) = (5pi)/(3)` rad.
