The range of wavelengths for visible light is from 3.9*10^-7m. What is the corresponding range of frequencies for visible light

from 7.69*10¹⁵ Hz

Explanation:

Frequency: This can be defined as the number of complete cycle a wave complete in one seconds, the S. I unit of frequency is Hertz (Hz).

From the question,

v = λf ... Equation 1

Where v = speed of visible light in air, λ = wave length of visible light, f = frequency of visible light.

make f the subject of the equation

f = v/λ ... Equation 2

Note: all electromagnetic wave have the same speed = 3*10⁸ m/s

Given: v = 3*10⁸ m/s, λ = from 3.9*10⁻⁷ m

Substitute into equation 2

f = 3*10⁸ / 3.9*10⁻⁷

f = 7.69*10¹⁵ Hz

Hence the range of the frequencies for visible light = from 7.69*10¹⁵ Hz
