Physics 2017 JAMB Past Questions - Question 15: which of the following pairs of light rays shows the widest separation the spectrum of white light?
Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
B
Explanation
To determine which pair of light rays shows the widest separation in the spectrum of white light, we need to consider the phenomenon of dispersion. Dispersion occurs when white light passes through a prism or a diffraction grating, causing the different colors of light to spread out or separate.
The amount of separation depends on the angle at which the light enters and exits the prism or diffraction grating. The greater the angle, the wider the separation of colors.
Therefore, the pair of light rays that would show the widest separation in the spectrum of white light would be the rays that enter and exit the prism or diffraction grating at the largest angle.
