State the laws of reflection.
Angle of incidence is equal to the angle of reflection.
Draw a diagram showing the reflection of a light ray from a plane mirror. Label on it the incident ray, the reflected ray, the normal, the angle of incidence i and the angle of reflection r.
According to the law of reflection :
A student does the experiment on tracing the path of a ray of light passing through a rectangular glass slab for different angles of incidence. He can get a correct measure of the angle of incidence and the angle of emergence by following the labelling indicated in figure.
Look at the figure. Can the image of the child in it be obtained on a screen?
Plane mirrors are arranged parallel to each other to get ______.
If the angle of incidence i = 0, the angle of reflection r = ______.
