Answer 2

Types of Mirrors:

1. Curved Mirrors
a) A convex mirror, which bulges outward, reflects at a wider angle near its edges than at its center, creating a slightly distorted image that's smaller than actual size. 
b) one that has its center further away from incoming light than its edges is called a concave mirror. 

2.Flat mirror
a) Flat mirror is also known as plane mirror. Sine flat /plant mirror is a smooth surface, specular reflection will occur when light comes by, which means the angle of incidence equals the angle of reflection from the normal line.
