Answer 2

There are 3 types of mirror
1. PLANE MIRROR
A plane mirror is a flat mirror that sends light out from itself in multiple directions.

2. CONCAVE MIRROR
A convex mirror works like a concave lens. It curves light away from its middle, like the outside portion of a bowl. This type of mirror will produce only smaller and virtual images.

3. CONVEX MIRROR
A concave mirror works much like a convex lens. It bends light further away in the middle, more like the inside of a bowl.

There 2 types of lens
1. CONCAVE LENS
Concave lenses are thicker on the ends and thinner in the middle. They divert light rays away from a focal point and only create virtual or smaller images.

2. CONVEX LENS
A convex lens is thicker in the middle than on its outside edge.
