Mirrors

This topic is claimed by Ethan Lyons

Mirrors are objects which only have one surface that is used to reflect light. This will result in the creation of images.

Types of Images

Real Images

Real images form when the rays of light converge at a focal point that actually exists. For mirrors, this means that an image is real if it is formed on the same side as the object. This means that the image is able to be projected onto another object.

Virtual Images

Virtual images form when the rays of light converge at a point that does not actually exist. For mirrors, this means that the light converges at a place behind (or through) the mirror, which is not an actual location. This means that we can see the image but it is not able to be projected. Mirrors create virtual images when the light rays converge in a spot that is on the opposite side of the object.

Basic Types

There are multiple types of mirrors which each act with light differently.

Flat Mirrors

Flat mirrors are mirrors that have flat surfaces, hence the name. We know that light will always travel in a straight line regardless of its medium. Therefore, when light comes into contact with a flat mirror, it will reflect at the same angle. This means that the angle of the incident ray will always be the same as the angle of the reflecting ray. Additionally, these will always produce virtual objects.

Convex Mirrors

A convex mirror is a mirror in which the focal point of the mirror is on the opposite side of the mirror as the object.

Concave Mirrors

A concave mirror is a mirror that has its focal point on the same side of the mirror as the object.
