A plane mirror is a reflective surface that divides incoming light rays into two parallel rays. These parallel rays then diverge at equal angles, forming an image of the object on the opposite side of the mirror.
Key features of the formation of an image by a plane mirror:
The rays of light travel from the object to the mirror at the same speed.
The mirror reflects these rays of light in a way that creates an image on the opposite side.
The distance between the object and the mirror is equal to the distance between the object and the image.
The image is always virtual, meaning it is not real but appears to be formed in the same place as the object.
The size and position of the image depend on the position and size of the object.
Additional points to consider:
The plane mirror is an ideal surface, meaning it has no curvature.
The image is formed on a screen or other light-sensitive surface.
The image is always upright and has the same magnification as the object.
The image is formed on both the near and far sides of the mirror.
Examples:
A ray of light from a bird's eye is reflected by a plane mirror and forms an image on the ground.
A ray of light from a point object is reflected by a plane mirror and forms an image on the same plane as the object.
A ray of light from a point object is reflected by a plane mirror and forms an image on the opposite side of the mirror
