A wave of frequency 500 Hz has a velocity 300 m/s. The distance between two nearest points which are `60^(@)` out of phase , is ………… .

A

0.2 m

B

0.1 m

C

0.4 m

D

0.5 m

Text Solution

Verified by Experts

The correct Answer is:
A
0.1 m
`lambda = (300)/(500) = 0.6` m
`Delta x = (lambda)/(2pi) * Delta phi = (0.6)/(2pi) * (pi)/(3) = 0.1 ` m
