उत्तर
In an experiment to trace the path of a ray of light through a triangular glass prism, a student would observe that the emergent ray gets deviated and bends towards the thicker part (base) of the prism.
Hence, the correct answer is option (d).

Describe an activity to show that colours of white light splitted by a glass prism can be recombined to get white light by another identical glass prism. Also draw ray diagram to show the recombination of the spectrum of white light.
Draw a ray diagram to show the dispersion of white light.
What are the seven colours seen in a rainbow?
A beam of white light is shone onto a glass prism. The light cannot be:
(a) deviated
(b) dispersed
(c) focused
(d) refracted
A ray of light moving from an optically rarer to a denser medium
A ray of white light falls on a prism. Draw a ray diagram to show that the prism disperses the white light.
The diagram below shows the path taken by a narrow beam of yellow monochromatic light passing through an equiangular glass prism. If the yellow light is replaced by a narrow beam of white light incident at the same angle, draw another diagram to show the passage of white light through the prism and label it to show the effect of prism on the white light.

Assertion: We can see the rainbow in the sky when the rain starts falling after a spell of bright sunlight.
Reason: The rainbow is formed due to the dispersion of light.
