Concave mirror forms the real image of a...

Concave mirror forms the real image of a point source lying on the optical axis at a distance of 50 cm from the mirror. The focal length of the mirror is 25 cm. The mirror is cut into and its halves are drawn a distance of 1 cm apart in a direction perpendicular to the optical axis. How will the image formed by the halves of the mirror be arranged?

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Using mirror formula,` (1/v+1/u=1/f)`
`1/v-1/50=(-1)/25`
`:. v=-50cm`
` m=-(v/u)=-1`.

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.
