Question

Calculate the frequency of an indigo light wave with the wavelength of 4.45 x 10^-7 m. The speed of light is 3.0 x 10^8.

^ meaning to the power

Answer 1

6.74 x 10¹⁴Hz

Step-by-step 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
