Luminous: Objects that emit light of their own are called luminous. For example, the Sun.

Mirror: A polished, shining surface that reflects most of the light that falls on it is called a mirror. We use mirrors to see our reflections.

Opaque: An object that doesn’t allow light to pass through it, so the things behind it are not visible is called as opaque. For example, a wooden block.

Pinhole camera: A camera that does not have a lens and has a pinhole that works as aperture and inverted objects are seen on the opposite side of the box, is called as pinhole camera.

Reflection: The bouncing off of light without absorption, when it falls on any surface is called reflection. Mirror reflects most of the light that falls on its surface.

Shadow: Shadows are dark patches formed behind the object when light hits an object. They are formed because light travels in a straight line and when it hits the object, most of it bounces back forming a shadow behind it.

Translucent: An object that allows light to pass through it only partially is called translucent. An oiled paper is translucent.

Transparent: An object that allows light to pass though it so that objects behind it are visible is called transparent. A clear window is transparent.
