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

What is meant by the 'angle of incidence' and the 'angle of refraction' for a ray of light ? Draw a labelled ray diagram to show the angle of incidence and the angle of refraction for a refracted ray of light.
Glass has refractive index u with respect to air and the critical angle for a ray of light going from glass to air is θ. If a ray of light is incident from air on the glasses with the angle of incidence θ, the corresponding angle of refraction is
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. [3 MARKS]
