Question

A person standing in front of a mirror finds that his image is larger than himself. This implies that the mirror is?
(A) convex
(B) concave
(C) plane
(D) Plano convex

Answer 1

Hint A mirror is the object which reflects the exact image of the object which is placed in front of the mirror, and some types of the mirror shows the image of the object is bigger than the original size of the object and some mirror shows the image of the object is smaller than the original size of the object.

Complete step by step answer
A mirror is an intelligent surface that ricochets off light-delivering either a genuine picture or a virtual picture. At the point when an item is set before a mirror, the picture of a similar article is found in the mirror. The article is the wellspring of the occurrence beams and the picture is shaped by the reflected beams. In view of the communication of light, the pictures are delegated either a genuine picture or a virtual picture. A genuine picture happens when the light beams really converge while virtual pictures happen because of the evident uniqueness of light beams from a point.
Beam outlines assist us with following the way of the light for the individual to see a point on the picture of an article. Beam chart utilizes lines with bolts to speak to the occurrence beam and the reflected beam. It additionally causes us to follow the heading wherein the light voyages. In the event that an empty circle is cut into parts and the external surface of the cut part is painted, at that point it turns into a mirror with its inward surface as the reflecting surface. This kind of mirror is known as a sunken mirror.
The concave mirror is the only mirror which shows the image of the object is bigger than the original size of the object.

Hence, the option (B) is the correct answer.

Note
Light joins at a moment that it strikes and reflects back from the reflecting surface of the curved mirror. Henceforth, it is otherwise called a joining mirror. At the point when the inward mirror is set near the article, an amplified and virtual picture is acquired. Notwithstanding, in the event that we increment the separation between the article and the mirror, at that point the size of the picture lessens and a genuine picture is shaped. The picture shaped by the sunken mirror can be little or enormous or can be genuine or virtual.
