PHYSICS TRUE / FALSE

Image is formed by a mirror due to refraction of light.

A virtual image formed by a spherical mirror is always erect and situated behind the mirror.

The focal length of a convex mirror is equal to its radius of curvature.

A convex mirror is used as a shaving mirror.

Rays of light incident parallel to the principal axis pass through the focus after reflection from a concave mirror.

The angle formed between the normal and the refracted ray is known as the angle of incidence.

At the point of incidence, a line drawn at right angles to the surface, separating the two media, is called the normal.

Light travels in the same straight line path while passing through different media.

Light travels at a lower speed in water than in air.

The depth of a pond when seen from above appears to be less.

The speed of light is more in glass than in water.

A ray of light when passes from glass to air, bends towards the normal.

Water is optically denser than glass.
