Question

Which of the following diagrams is not correct?
(A)

(B)

(C)

(D)

Answer 1

In general, there are two types of mirrors, they are concave mirror and convex mirror. The construction of these two mirrors are different and the working of the two mirrors are also different. Here some ray diagrams are given according to the working of the mirror, the solution is determined.

Complete answer:
Concave mirror:
A concave mirror, or converging mirror, has a reflecting surface that is recessed internally (away from the episode light). Sunken mirrors mirror light internal to one point of convergence. They are utilized to shine light. In contrast to raised mirrors, inward mirrors show distinctive picture types relying upon the separation between the article and the mirror.
These mirrors are designated "combining mirrors" since they will in general gather light that falls on them, pulling together equal approaching beams toward a core interest. This is on the grounds that the light is reflected at various points at various spots on the mirror as the typical to the mirror surface contrasts at each spot.

Convex mirror:
A convex mirror or diverging mirror is a bended mirror where the intelligent surface lumps towards the light source.[1] Convex mirrors mirror light outwards; accordingly, they are not used to shine light. Such mirrors consistently structure a virtual picture, since the point of convergence (F) and the focal point of bend (2F) are both non-existent focuses "inside" the mirror that can't be reached. Subsequently, pictures framed by these mirrors can't be extended on a screen, since the picture is inside the mirror. The picture is more modest than the item, yet gets bigger as the article moves toward the mirror. A collimated (equal) light emission wanders (spreads out) after reflection from an arched mirror, since the typical surface contrasts at each spot on the mirror.

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

Note:
The concave mirror is the type of mirror which combines the light rays, so it is called a converging mirror. And the convex mirror is the type of mirror which spreads the light rays, so it is called a diverging mirror. When the ray of light passes in parallel to the centre axis of the convex mirror, then the rays pass through the centre of curvature.
