If Wavelength is 363X10^-9m Find the frequency

Given parameters:

Wavelength = 363 x 10⁻⁹m

Unknown:

Frequency  = ?

The frequency of a wave is the number of waves passing through a point per unit of time.

In the electromagnetic spectrum, to find wave frequency, we use the expression below;

          V  = f π

where V is the wave velocity

f is the wave frequency

π is the wavelength

Often times, we use the velocity of light = 3 x 10⁸m/s

Now input the parameters and solve for f;

  3 x 10⁸m/s   =  f x  363 x 10⁻⁹m

     f  =   = 1.21 x 10⁻¹⁵Hz

The frequency of the wave is 1.21 x 10⁻¹⁵Hz
