Answer:
Uses of Plane Mirror :
They are used as looking glass.
They are used in solar cookers.
They are also used in constructing periscope which is used in submarines.
They are also used to make kaleidoscope, a toy which produces beautiful patterns.
They are also used in various scientific instruments.
Answer:
plane mirror is a mirror with a flat (planar) reflective surface.For light rays striking a plane mirror, the angle of reflection equals the angle of incidence.The angle of the incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface). Therefore, the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects.
Plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object. Virtual objects produce real images, however. The focal length of a plane mirror is infinity; its optical power is zero.
