Physics 2003 JAMB Past Questions - Question 36: Which of the following pairs of light rays shows the widest separation in the spectrum of white light?

Correct Answer

A

Explanation

The widest separation in the spectrum of white light occurs between red and violet light. White light is made up of a spectrum of colors, with red having the longest wavelength and violet having the shortest wavelength. So, the pair of light rays that shows the widest separation in the spectrum of white light is:

1. Red (longest wavelength) and Violet (shortest wavelength)

The visible spectrum of white light, in order of increasing wavelength, is generally described as follows:

1. Violet
2. Blue
3. Green
4. Yellow
5. Orange
6. Red

The separation between red and violet is the widest in the visible spectrum.
