Sound waves of frequency 600 H(Z) fall n...

Sound waves of frequency `600 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

`c = v lamda`
`:. lamda = (c)/(v) = (330)/(660) = 0.5 m`
The antinode will be at a distance of
`(lamda)/(4)=(0.5)/(4) = 0.125 m`.
