Answer:
5.5Hz
Explanation:
Given parameters:
Wavelength of green light = 5.5 x 10⁷m
Unknown:
Frequency of the wave = ?
Solution;
Green light is a part of the electromagnetic spectrum. The speed of all these rays in free space is 3 x 10⁸m/s
So;
V = fλ
V is the speed
f is the frequency
λ is the wavelength;
So;
F = [tex]\frac{V}{wavelength}[/tex]
Insert the parameters and solve;
F = [tex]\frac{3 x 10^{8} }{5.5 x 10^{7} }[/tex] = 5.5Hz
