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 = [tex]\frac{363 x 10^{-9} }{3 x 10^{8} }[/tex] = 1.21 x 10⁻¹⁵Hz
The frequency of the wave is 1.21 x 10⁻¹⁵Hz
