Arrange the following steps in sequential order to verify laws of reflection of light.
(A) Place a mirror on MM' and looking at the pins P and Q from the other side of the normal, observe their images.
(B) Fix a white paper to a drawing board and draw a straight line MM' and a line ON perpendicular to MM' on the paper.
(C) Fix two more pins P' and Q' in line with the images of the pins P and Q.
(D) Draw a line PO such that it makes suitable acute angle with the normal and fix two pins P and Q on the line, which is the incident ray.
(E) Measure `anglePON`, the angle of incidence and `angle(P'ON)`, the angle of reflection.
(F) Remove the plane mirror and join P' and O. OP' is the reflected ray.
(G) Repeat the experiment for different angles of incidence and tabulate the results.

Answer

C

Explanation

(A) Fix a white paper to a drawing board and draw a straight line MM. and a line ON perpendicular to MM. on the paper (b).
(B) Place a mirror on MM. and looking at the pins
P and Q from the other side of the normal, observe their images (a).
(C) Draw a line PO such that it makes suitable acute angle with the normal and fix two pins P and Q on the line, which is the incident ray (d).
(D) Fix two more pins P. and Q. in line with the images of the pins P and Q (c).
(E) Measure FPON, the angle of incidence and FP.ON, the angle of reflection (e).
(F) Remove the plane mirror and join P and O. OP. is the reflected ray .
(G) Repeat the experiment for different angles of incident and tabulate the results (g).
