Question

An incident ray strikes a plane mirror at an
angle of 15° with the
mirror find the angle between
incident
ray
and reflected ray​

Answer 1

${150}^{0}$

Explanation:

incidence ray makes

${75}^{0}$

angle with normal at the point of incidence .

and angle of incidence is equal to angle of reflection.

angle of reflection is also 75 deg

therefore angle between incidence ray and reflected ray is 150 deg
