A tuning fork of frequency 220Hz produces sound waves of wavelength 1.5m in air at NTP. Calculate the increase in wavelength, when temperature of air in `27^(@)C`.

Text Solution

Verified by Experts

`v_(0)=vlambda_(0)=220xx1.5=330m//s`
`v_(t)=v_(0)sqrt((T)/(T_(0)))=330sqrt((273+27)/(273))=345.93m//s`
`lambda_(t)=(v_(t))/(v)=(345.93)/(220)=1.57m`
`y_(t)-lambda_(0)=1.57-1.5=0.07m`
