The diagram given below in Fig. 5.38 shows a ray of light AO falling on a surface separating two media. Draw the refracted ray in each, case.

(c)

Draw a diagram showing the refraction of a light ray from water to glass. Label on it the incident ray, the angle of incidence (i), and the angle of refraction (r).

A ray of light falls normally on a glass slab. What is the angle of incidence?

A ray of light travels from a rarer medium to a denser medium. How will it bend?
