Answer:
7.3 x 10¹⁴Hz
Explanation:
Given parameters:
Wavelength = 4.105 x 10⁻⁷m
Unknown:
Frequency of the light =?
Solution:
The frequency, wavelength and speed of a wave are related using the expression below;
C = f λ
C is the speed of light = 3 x 10⁸
f is the frequency
λ is the wavelength
3 x 10⁸ = f x 4.105 x 10⁻⁷
f = [tex]\frac{3 x 10^{8} }{4.105 x 10^{-7} }[/tex] = 7.3 x 10¹⁴Hz
