Solve this:
Q.25. A student performs an experiment for verification of laws of reflection and records the angle of incidence and angle of reflection. He then proceeds to plot a graph between the angle of incidence and the angle of reflection. The graph is likely to be :
(a) straight line
(b) zig-lag line
(c) hyperbola
(d) parabola

Dear student,
According to the law of reflection angle of incidence is always equal to the angle of reflection.
So  the graph will look like this,

As it is clear the graph is a straight line, so option (a) is correct.

Regards
