Question

Aakash is towards east of source and Vikash is towards west of source. if Aakash received sound at speed of 340 meter per second and Vikash received the same sound at 320 m/s and source lie along the same straight east to west line fine velocity of sound and velocity of wind flowing​

Answer 1

Answer:

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
