Explanation:
When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light. ... However, because light can travel through space, it cannot be a matter wave, like sound or water waves.
When parallel light rays hit a concave mirror they reflect inwards towards a focal point. Each individual ray is still reflecting at the same angle as it hits that small part of the surface. ... Light rays travel towards the mirror in a straight line and are reflected inwards to meet at a point called the focal point. Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy.
Also, when light is reflected from a mirror, it bounces off at the same angle in the opposite direction from which it hit. ... If the surface is concave, or curved inward, a group of light rays from a distant source is reflected back toward a single location known as the focal point
