A concave mirror forms real image of a point source lying on the optical axis at a distance of 50cm from the mirror. The focal length of the mirror is 25cm. The mirror is cut in two, and its halves are drawn at a distance of 1 cm apart in a direction perpendicular to the optical axis.

Q. In the given situation, if the two halves are each rotated (before being separated) about S by `90^(@)`, with reference to original position, then the distance between the two images will be

A

0.5cm

B

2cm

C

1cm

D

zero

Text Solution

Verified by Experts

The correct Answer is:
d.
Both the mirrors will be having the common object at their center of curvature. Hence the image position also coincides.

A concave mirror forms real image of a point source lying on the optical axis at a distance of 50cm from the mirror. The focal length of the mirror is 25cm. The mirror is cut in two, and its halves are drawn at a distance of 1 cm apart in a direction perpendicular to the optical axis. Q. Two statements are provided. Choose which is true and which is false. Statement I: Image formed by half cut mirror has just half the intensity as that of the intensity of image formed by complete mirror. Statement II: More the lateral separation between the two halves of the mirror, less will be the separation between the two images, as show in the given situation.
