Answer 2

Answer:

An image in a plane mirror doesn't change in size at all; it is always of the same size as that of the object. An image in a mirror can be seen without a screen, whereas it is mandatory to have a screen to form a shadow. Shadows are formed when opaque objects obstruct the path of light.
