Answer:
6.74 x 10¹⁴Hz
Explanation:
Given parameters:
Wavelength = 4.45 x 10⁻⁷m
Speed of light = 3 x 10⁸m/s
Unknown:
The frequency of the indigo light = ?
Solution:
To solve this problem, we use the expression below;
V = f ∧
V is the sped of light
f is the frequency
∧ is the wavelength
Now insert the parameters and solve;
3 x 10⁸ = f x 4.45 x 10⁻⁷
f = 6.74 x 10¹⁴Hz
