Question

"Calculate the frequency of infrared light with wavelength of 9.50 x 10-7m"

Answer 1

Answer:

The frequency of the infrared light is approximately 3.156 × 10¹⁴ Hz

Explanation:

Given that the wavelength of infrared light, λ = 9.50 × 10⁻⁷ m, we have;

The speed of light (which is constant), c = v × λ = 299,792,458 m

Where v = The frequency of the infrared light, we have;

v = c/λ = 299,792,458/(9.50 × 10⁻⁷) ≈ 3.156 × 10¹⁴ Hz

The frequency of the infrared light = v ≈ 3.156 × 10¹⁴ Hz.
