The distance between two consecutive conden sations in the sound wave propagating in air is im. If the velocity of the sound in air is 340 `ms^(-1)`, what would be the frequency of this wave?

A

680 Hz

B

340 Hz

C

170 Hz

D

85 Hz

Text Solution

Verified by Experts

Wavelength `lambda` = Distance between
two consecutive
condensations
=2m
Frequency `v=(u)/(lambda)=(340)/(2)=170 Hz`
170 Hz
