Two sound waves each of frequency 500Hz ...

Two sound waves each of frequency 500Hz are travelling along the same line in opposite direction . If the speed of sound in air is 350 m/s. find the distance between the consecutive antinodes of the resulting stationary wave.

A

0.15m

B

0.25m

C

0.35m

D

0.45m

Text Solution

Verified by Experts

The correct Answer is:
C
`lamda = v/n = 350/500 = 35/50 = 0.7`
This distance between antinode to antinode is
`=lamda/2 = (0.7)/(2) = 0.35m`
