1. The light first passes through a tough protective sheet called the cornea, and then moves into the lens. This adjustable structure bends the light, focusing it down to a point on the retina, at the back of the eye. The retina is covered in millions of light-sensitive receptors known as rods and cones.
2. beam of light
A single wave of light is called a ray. Bundle of light rays or a collection of rays is called beam of light.
3.Light that is produced by a living organism's body is called bioluminescence (say: by-oh-loo-muh-nes-ens). Depending on the species, they may use their glow to attract prey, warn off other animals, scare predators, or to communicate with each other.

6. A plane mirror forms an image which is erect and of the same size as the object. A convex mirror forms a virtual, diminished, and upright image and therefore, covers a larger area of view. Its field of view is very large. A convex lens can form a magnified image of the object.
