Question

State the nature , position and relative size of the image formed by a convex mirror
when object is (i) at infinity and (ii) between infinity and pole of the mirror .​

Answer 1

Required Answers:-

(i) The nature, position and relative size of the image formed by a convex mirror when the object is placed at infinity.

⟶ According to the first ray diagram of a convex mirror, any ray from infinity, which is parallel to the principal axis will diverge in such a way that if we retrace the reflected ray towards it's backward, it will meét at the focus behind the mirror.

• Position of the image - Behind the mirror at F
• Nature of the image - Virtual & Erect
• Size of the image - highly diminished (or point sized)

(ii) The nature, position and relative size of the image formed by a convex mirror when object is at between infinity and pole of the mirror.

⟶ According to the ray diagrams of convex mirror if we place object anywhere between pole and focus, the image will always be formed between Pole and focus behind the mirror.

• Position of the image - Behind the mirror between P and F
• Nature of the image - Virtual & Erect
• Size of the image - Diminished
