Question

the speed of sound in air is 340 m/s and in water 1440 m/s it takes 2 sec for sound to reach a certain distance from the source placed in air find the distance and find time in water sound take to reach same distance ​

Answer 1

Answer:

Given, (In air)

Velocity V=340m/s

Frequency f=20,000Hz

Wavelegth λ=?

V=f.λ

λ=  V /F   =  340/ 20,000  = 0.017Hz

Also, Given (in Water)

Velocity, V=1480m/s

Frequencyf=20,000Hz

wavelength, λ=?

V=f.λ

λ=  V /F  = 1480 / 20,000  =0.074Hz
