Question

Question 1 (1 point)
Read the paragraph and answer the question:

When the light rays travel through different medium with different optical densities, the light rays change their direction at the boundary between the media. This is because the speed of light is different in different media. When a beam of light is passed through a triangular prism , the white light splits into a band of 7 colours. The reason for dispersion is that a glass prism bends different colours by different amounts.

If medium A is optically denser than medium B , then the speed of light is

Question 1 options:

a) the same in both the medium.


b) higher in medium B than in medium A .


c) higher in medium A than in medium B.


d) higher in medium A or B depending on which medium is thicker.
