Solution
Frequency: The number of complete waves or cycles produced in one second.
Wavelength: The minimum distance in which a sound wave repeats itself.
Velocity of a wave: The distance travelled by a wave in one second.
We know the relation between velocity, frequency, and wavelength
ν = f × λ,
where ν is the velocity of sound, F the frequency, and λ the wavelength.
