Question

A virtual image is formed by the plane mirror. When the pencil of light is incident on the mirror, then the incident ray on the mirror is:
A. Diverging
B. Parallel
C. Converging
D. All of the above

Answer 1

Always a mirror will produce a virtual image of an object that is real whether it is a convex or concave mirror. The parallel beam of the ray is projected on the plane mirror and gets reflected without any deviation. To determine whether the incident rays are parallel, diverging, or converging by applying this logic.

Complete answer:
The focal length of a mirror is infinity. The rays will get deflected and if the parallel beam of light falls on the surface of the plane they will not have any images. Plane mirrors usually form virtual images. The plane mirror forms a real image when we can arrange it in such a way. In a plane mirror always, a real object will produce a virtual image and that is because the reflected rays diverge.
They are relative to each other because the light hitting the mirror reflects back at the same angle. All of them shift the same amount so the rays will be unaffected. When a diverging ray hits a mirror then they will be diverging and a real image will not be formed. Similarly, if a converging ray hits a mirror they will converge and form a real image.
Hence, Then the incident ray on the mirrors is converging.

Note: An object is virtual then that means the object is infinity because the focal length of a plane mirror is infinity.
The image is formed by a plane mirror that is always virtually upright and of the same shape and size as the object it is reflecting.
The light rays appear to come when a virtual image is a copy of an object formed at the location.
