Write the following steps in sequential order to determine nature of the image formed by a concave mirror where an object is placed at the centre of curvature with the help of a ray diagram.
(A) Mark the position of the object infornt of the mirror at the centre of curvature.
(B) Draw a diagram, which represents a concave mirror.
(C) Draw two lines one passing through F and another line parallel to the principal axis and draw the path of the reflected rays.
(D) Draw the principal axis and mark the centre of curvature and principal focus.
(E) Mark the position of the image and study its nature.

Options

A. CADBE
B. ECBAD
C. CBAED
D. CEABD

Answer

D

Explanation

Draw a concave mirror and mark the pole, the principal focus and the centre of curvature of the mirror. Draw the principal axis of the mirror and mark the position of the object between the principal focus and pole of the mirror. Draw two incident light rays from the object, one parallel to the principal axis and the other coming from the centre of curvature, and draw the corresponding reflected rays. These reflecting light rays are diverging. So, draw the extended lines till they intersect. Mark the image at a point where the extended light rays intersect and write the nature of the image.
