Question

The human eye is very sensitive to light having a wavelength of 5.51 ✕ 10-7 m, which is in the green-yellow region of the visible electromagnetic spectrum. What is the frequency of this light?

Answer 1

`F = 5.44 * 10^(14)\ Hz`

Step-by-step explanation:

Given

`Wavelength = 5.51 * 10^(-7)m`

Required

Determine the Frequency (F)

Represent the wavelength with W

The relationship between W and F is:

`F = (c)/(W)`

Where

c = Speed of Light

`c = 3 * 10^8 m/s`

Substitute values for c and W

`F = (3 * 10^8)/(5.51 * 10^(-7))`

`F = (3 * 10^(8+7))/(5.51)`

`F = 0.5444646098 * 10^(8+7)`

`F = 0.5444646098 * 10^(15)`

`F = 5.444646098 * 10^(14)`

`F = 5.44 * 10^(14)\ Hz`
