The properties of the image formed by a plane mirror & Light reflection features

When you look at the mirror, you can see an image of your face, You observe a whole image of the surrounding environment that is formed on the surface of still water, The surface of still water can act as an almost perfect mirror, All what happened as a result of the reflection of light.

Light reflection

The light reflection takes place when the light rays directed from a source of light to an object reflect from it in the same medium then you can see the reflected light rays to your eyes.

The light reflection is the phenomenon of the light bouncing off in the same medium when it meets a reflecting surface, The light reflection takes place via the reflecting surface as the mirrors.

The light reflection in the mirrors is governed by two principal laws which are the angle of incidence equals the angle of reflection, And you know that the incident light ray, the reflected light ray and the normal to the surface of reflection at the incidence point should all lie in one plane perpendicular to the reflecting surface.

The incident light ray is the light ray that falls on the reflecting surface, The reflecting light ray is the light ray that bounces from the reflecting surface.

The incidence angle is the angle between the incident light ray and the normal, The reflection angle is the angle between the reflected light ray and the normal.

Any incident light ray that falls perpendicular on a reflecting surface, reflects on itself as the angle of incidence and the angle of reflection equals zero.

The plane mirror

The plane mirror

The mirrors are the reflecting surface for the light, There are two main types of mirrors which are the plane mirror and the spherical mirrors, The spherical mirrors are the concave mirrors and the convex mirror.

The plane mirror is a piece of plane glass, painted from behind with a thin layer of silver metal to give the glass a bright surface that reflects most of the incident rays on it.

The plane mirror is the mirror with a planer and flat reflective surface, It makes the image of the objects in front of it, The images appear behind the plane at which the mirror lies, The straight line drawn from the part of an object to the part of its image makes a right angle with, and it is bisected by the surface of the plane mirror.

The image formed by the plane mirror is always virtual, upright and of the same shape and size as the object is reflecting, The virtual image is a copy of the object formed at the location from which the light rays come, the image is a laterally inverted mirror image of the object.

The virtual objects produce the real images, however, The focal length of a plane mirror is infinity, Its optical power is zero, The image in the plane mirrors is a virtual image, The virtual images are images that are formed in the locations where the light does not actually reach.

The properties of the image formed by a plane mirror

The image is upright (erect), The image is equal to the object in the size, The image is laterally inverted ( reversed ) and the image can not be received on a screen as it is virtual.

The distance between the object and the mirror is equal to the distance between the image and the mirror, The straight line joining the object to its image is perpendicular to the surface of the mirror.
