Question

You want to register your name for an examination. For registration purposes, you need a passport-size photograph of yourself. When you went to a studio, the photographer told you to sit on a chair in front of a white screen in the room.

Assertion (A): This is purposefully done so that you as an object should stand beyond the centre of curvature of the camera lens, but surely not at an infinite distance.

Reason (R): The characteristics of the image formed are that it can be taken on a screen and is also diminished in size.

विकल्प

• Both A and R are true, and R is the correct explanation of A.

• Both A and R are true, and R is not the correct explanation of A.

• A is true, but R is false.

• Both A and R are false.

Answer 1

Both A and R are true, and R is the correct explanation of A.

Explanation:

Both statements are true. A camera forms a real, diminished image on its film or sensor when the object is placed beyond twice the focal length of the lens. The reason describes the image properties that require the object to be at this position.
