In the air, the velocity of sound wave is 340 `ms^(-1)` and wavelength is 3.4 m. Now a wave of the same frequency propagates in water, then what would be its wavelength ? (Take velocity of wave in water as 1500 `ms^(-1)`.)

Options

A. 15 m
B. 34 m
C. 3.4 m
D. 1.5 m

Explanation

Frequency `v=(v)/(lambda)=(340)/(3.4)=100 Hz`
Now. wavelength of the wave in water,
`lambda.=(u.)/(v.)=(1500)/(100)=15m`
15 m
