(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.

Text Solution

Verified by Experts

The correct Answer is:
D
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.

    Draw ray diagram showing the image formation by a concave mirror when an object is placed: At infinity

    Draw the ray diagram and also state the position, the relative size and the nature of image formed by a concave mirror when the object is placed at the centre of curvature of the mirror.

    With the help of a ray diagram, determine the position, nature and size of the image formed of an object placed at the centre of curvature of a concave mirror.

    Write the following steps in sequential order to determine nature of the image formed by a concave mirror when an object is placed between the pole and the prinicpal focus of the mirror, with the help of a ray diagram. (A) Draw two incident light rays, one parallel to the principal axis and the other coming from the center of curvature and draw the paths of the reflected light rays. (B) The reflected light rays are diverging. So, draw the extended lines till they intersect. (C) Draw a concave mirror and mark the pole, the principal focus, the centre of curvature of the mirror. (D) Mark the image at the point of intersection of the extended light rays and write the nature of the image. (E) Draw the principal axis and mark the position of the object on the principal axis between the pole and the principal focus.
