Given that sound travels in air at 340m/sec, find the wavelength of the waves in air produced by 20 kHz sound source. If the some source is put in a water tank, what would be the wavelength of the sound waves in water?
Speed of sound in water is 1480m/s

Answer:
Given, (in air)
Velocity V = 340m / s
Frequency f = 20,000 Hz
Wavelength = ?
V = f.Wavlength
Wavelength = V / F
= 340 / 20,000
= 0.017 Hz
Also Given (in water)
Velocity, V = 1480m / s
Frequency f = 20,000 Hz
Wavelength = ?
V = F. Wavelenght
Wavelength= V / F
= 1480 / 20,000
= 0.074 Hz
