Speed of sound in air is `330m//s`.Find maximum and minimum wavelength of audible sound in air.

Text Solution

Verified by Experts

The correct Answer is:
A, B
Frequency of audible sound varies from `20Hz` to `20000Hz`.
Speed of all frequencies in air will be same `(=330m//s)`
`:.lambda_min=(v)/(f_(max))=330/20000`
`=0.0165m`
Similarly, `lambda_max=(v)/(f_(min))=330/20`
=`16.5m`
