Question

A man heard an echo of his own voice from a distant cliff after 1.5 seconds.If the speed of sound in air is 330m/s.Find the distance of the cliff from the man​

Answer 1

Answer:

247.5m

Given,T=1.5secs

so,f=T–¹=1/1.5

1. V=Frequency*wavelength
2. wavelength=V/F
3. wavelength=330*15/10
4. wavelength=495m

• Then,
• distance of the cliff from the man is given by= wavelength/2
• =495/2m
• =247.5m
