Explanation:
Place the paper on the board and fix.
Place the mirror vertically on the white sheet of paper and trace its edge.
Draw a line at right angles to the edge of the edge of the mirror to act as the normal- ON .
Stating with angle i as 30 degree , draw an incident ray and place two pins, P and Q along it as shown.
Answer:
Join P'Q' and produce the straight line to meet M. It is found that ∠i=∠r. This proves that angle of incidence is equal to angle of reflection. As the incident ray, the reflected ray and the normal lie in the plane of paper, therefore, they lie in the same place.
