Light is falling on surface S1 , S2, S3 as shown in Figure. Surfaces on which the angle of incidence is equal to the angle of reflection is/are

Light rays are falling on surfaces S1, S2 and S3 as shown. Choose the surface on which the laws of reflection of light is valid.1 point

The ___________ indicates how much of the light falling on a surface is reflected

Describe your observations about the relationship between the angle of incidence and angle of reflection.

Four parallel light rays hit a rough surface at different points, as shown in the diagram.Use the law of reflection to explain why the reflected rays have different directions.

A ray of light is incident towards a plane mirror at an angle of 63𝑜63 o with the mirror surface of the plane mirror. What will be the angle of reflection?
