Question

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.

Q: Which of the following statement is correct?

Question 2 options:

a) Speed of the light changes during refraction.


b) wavelength of the light will change.


c) frequency of the light changes.


d) speed of the light remains constant.
