An image formed by a plane mirror is always of the same size as that of the object.
explanation : you know as well, A plane is mirror with a flat reflecting surface. plane mirror follows law of reflection. i.e., angle of incidence = angle of reflection.
An object located in front of plane mirror forms an image behind of it.The image formed by a plane mirror is always virtual, it means that the light rays do not actually come from the image.
shape and size of the image is similar to object as you can see in figure.
so, size of image = size of object .
but distance of image from the mirror = - distance of object from the mirror.
[ here negative sign shows that image is formed just opposite direction of object ]
Answer:
An ‘image’ formed by a plane mirror is always of the ‘same size’ as that of the ‘object’.
Explanation:
A plane mirror is smooth piece of glass silvered on one side so that when light rays fall on it they are reflected to form the image of reflection of the object on which the rays were incident.
Since the ‘angle of incidence’ of light and the ‘angle of reflection’ are equal and they lie on the ‘same plane’, the image formed is of the same size as the object. The ‘image is virtual’ and laterally inverted. It cannot be ‘received on a screen’.
