Question

in a mateso, sound travels we i sand
air it travels zum in 10s. The state of the

wavelengths of sound in the two medio respectively​

Answer 1

Explanation:

Given, (In air)

Velocity V=340m/s

Frequency f=20,000Hz

Wavelegth

λ=?

V=f.λ

λ= F/V

= 20,000/340

=0.017Hz

Also, Given (in Water)

Velocity, V=1480m/s

Frequencyf=20,000Hz

wavelength, λ=?

V=F.λ

λ= F/V

=20,000/1480

=0.074Hz
