What is Reflection
The ratio of the velocity of light in a vacuum to its velocity in a specified medium.
Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.
When light bounces back from an object in the same medium after striking a surface, it is called Reflection.
Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye.
Reflection on a plane mirror
Regular reflection appears on a plane surface such as the surface of a mirror.
If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass.
The rough surface of a ground glass plate generally gives a diffuse reflection. However, if light from an object is incident on it at a low enough grazing angle, the rough surface behaves like an optically plane surface and causes specular reflection of the incident light, producing a reflected image of the object
Real Image
A real image is an image that is produced either due to reflection or refraction when the ray of light arises from an object and then converges to a certain point
A virtual image is an image that is produced when the ray of light arising from an object appears to strike at a certain definite point.

Characteristics of image formed on a Plane mirror
Plane mirrors only form virtual images.
The image formed or produced by a plane mirror is always of the same size as that of the object.
The images formed on a plane mirror are always laterally inverted.
VIRTUAL IMAGE
Applications of Plane Mirror
A plane mirror has several different uses and applications, including periscopes and kaleidoscopes, automobiles, shaving mirrors, dentists' mirror, torch lights, solar cookers and security-related purposes.
Virtual and erect.
Behind the mirror.
The size of the image is equal to the size of the object.
Physics mirrors are where light can be reflected and reconvened to form images. Two different types of mirror are concave and convex mirror with different properties.
