For a ray reflected on a plane mirror, find the ratio of sin i/sin r

Light from a torch is reflected by a white sheet of paper and a black polished mica sheet. Which of the two will produce a stronger reflected beam ?

Explain the following terms —

(a) plane mirror

(b) incident ray

(c) reflected ray

(d) angle of incidence

(e) angle of reflection.

Draw diagram/diagrams to show them.

Differentiate between reflection of light from a plane mirror and that from a plane wall.
