The product of (wavelength) x (frequency) is always the same number ... the wave's speed.
So if the wavelength is somehow reduced to 1/4 its original length, the frequency is immediately multiplied by 4 . That's the only way their product can remain the same.
The frequency increases by a factor of four when the wavelength is lowered by a factor of four.
Frequency is defined as the number of repetitions of a wave occurring waves in 1 second.
Frequency is given by the formula as,
[tex]\rm v = \lambda \times f[/tex]
If a wave travels at a constant speed the e frequency is inversely proportional to the wavelength.
if the wavelength is reduced by a factor of 4 then the frequency increases by a factor of 4.
Hence, the frequency increases by a factor of 4.
