How to prove that v = f x λ
The number of cycles / vibrations produced by a source of sound per second is called frequency. It is the rate at which sound wave is produced by the source.
F = 1/T where T is the time period and F is frequency…………………….(1)
The relationship of frequency and wavelength is :
Velocity of wave(v)= wavelength(λ)/time period(T)
from (1) we get :
Therefore we conclude that Frequency is inversely proportional to wavelength λ.
