A point source of light is placed in front of a plane mirror.
- a)Only the reflected rays close to the normal meet at a point when produced backward
- b)All the reflected rays meet at a point when produced backward
- c)Only the reflected rays making a small angle with the mirror, meet at a point when produced backward
- d)Light of different colours make different images
Correct answer is option 'B'. Can you explain this answer?

Plane mirror always forms a virtual image of the real object for all the rays emitted by the object. So, when a point source of light is placed in front of a plane mirror, all the reflected rays meet at a point when produced backward.
Option B is correct.

Explanation:
Plane Mirror and Reflection:
- A plane mirror reflects light according to the laws of reflection.
- The angle of incidence is equal to the angle of reflection, and the incident ray, the reflected ray, and the normal to the mirror all lie in the same plane.
Meeting Point of Reflected Rays:
- When a point source of light is placed in front of a plane mirror, all the reflected rays from the point source will appear to diverge from a virtual image located behind the mirror.
- If these reflected rays are extended backward, they will all meet at a point. This point is known as the virtual image of the point source of light.
- Therefore, all the reflected rays meet at a point when produced backward.
Explanation of Options:
- Option 'A' is incorrect because all the reflected rays, not just the ones close to the normal, meet at a point when produced backward.
- Option 'C' is incorrect because all the reflected rays, not just the ones making a small angle with the mirror, meet at a point when produced backward.
- Option 'D' is incorrect because light of different colors does not affect the meeting point of the reflected rays in this scenario.
Therefore, the correct answer is option 'B' - All the reflected rays meet at a point when produced backward.
