Draw diagrams to show the refraction of light from
- air to glass, and
- glass to air. In each diagram, label the incident ray, refracted ray, the angle of incidence
- and the angle of refraction (r).

उत्तर
Refraction of Light:
-
The incident ray from air to glass bends towards the normal PO, or refracted ray, and the OQ, or incident ray.
- It bends away from the normal PO, incident ray, and OQ, refracted ray, as it travels from glass to air.
