Draw a ray diagram to show the refraction of light through a glass prism.

On the diagram mark a) Incident angle b) emergent ray c) angle of deviation.

Draw a ray diagram showing the passage of light through a glass slab and label the following:

incident ray, normal, angle of incidence, refracted ray, angle of refraction, emergent ray, angle of emergence

(a) Draw a diagram to show the refraction of light through a glass prism. On this diagram, mark (i) incident ray (ii) emergent ray, and (iii) angle of deviation.
(b) What is a rainbow ? What are the two conditions necessary for the formation of arainbow in the sky ?
(c) What acts as tiny prisms in the formation of a rainbow ?
(d) Name the process which is involved in the formation of a rainbow.
(e) What are the seven colours seeen in a rainbow ?
