Sound waves of frequency `660 H_(Z)` fall normally on perfectly reflecting wall. The distance from the wall at which the air particles have the maximum amplitude of vibration is (speed of sound in air = `330 m//s`)

Text Solution

Verified by Experts

The correct Answer is:
0.125
`C=vlambda therefore lambda=c/v=330/660=0.5m`
The antinode will be at a distance of `lambda/4=0.5/4=0.125m`
