A bat emits ultrasound waves of frequency 1000kHz in air. If the sound meets a water surface, what is the wavelength of the transmitted sound in water? Speed of sound in air is `340ms^(-1)` and in water `1486ms^(-1)`

Text Solution

Verified by Experts

Given `f = 1000 xx 10^(3) Hz, v = 340ms^(-1), v _(W ) = 1486 ms^(-1)`
Wavelength of transmitted sound in water
`lambda' = ( v_(w))/( f) = (1486)/( 10^(6))`
`lambda = 1.486 xx 10^(-3) m`
