Which one of the following statesmeents is not correct with reference to reflection of light by a plane smooth surface?
Answers
The statement that is not correct with reference to reflection of light by a
plane smooth surface is:
(2) The angle of reflection is the angle between the reflected ray and the plane of the mirror.
When a ray of light is incident on a plane surface, it gets reflected.
The angle with which the ray strikes the surface is equal to the angle with which it is reflected back.
The angle of incidence is the angle between the incident ray and the normal at the point of incidence.
Similarly, The angle of reflection is the angle between the reflected ray and the normal.
All the three rays i.e. normal, incident ray and reflected ray lies on the same plane and at the same point.
