QN002426

A teacher places identical objects before a plane mirror and a convex mirror. Compared to the plane mirror image, the convex mirror image will be:

(A) Larger
(B) Same size
(C) Smaller
(D) Inverted

Correct Answer: C

Explanation:

A convex mirror forms a diminished image, whereas a plane mirror forms a same-sized image.

QN002427

According to the chapter, which mirror is used as a reflector in torches and vehicle headlights?

(A) Plane mirror
(B) Convex mirror
(C) Concave mirror
(D) Safety mirror

Question (38)

QN002428

Assertion: A convex mirror always forms an erect image. Reason: A convex mirror always forms a diminished image.

(A) Both Assertion and Reason are true, and Reason correctly explains Assertion.
(B) Both Assertion and Reason are true, but Reason does not correctly explain Assertion.
(C) Assertion is true, Reason is false.
(D) Assertion is false, Reason is true.

Correct Answer: B

Explanation:

Both statements are true, but being diminished does not explain why the image is erect.

Question (39)

QN002429

A student wants to identify a mirror only by observing images. Which observation confirms that the mirror is concave?

(A) Image is always erect and diminished
(B) Image is always same size
(C) Image changes from erect to inverted as distance changes
(D) Image is always erect and enlarged

QN002430

Bhāskara II's era astronomers observed reflected images of celestial objects using bowls of water. The observation depended on the same image-forming behaviour related to:

(A) Reflection from surfaces
(B) Magnetism
(C) Sound waves
(D) Heat conduction

Correct Answer: A

Explanation:

Reflected images are formed due to the phenomenon of reflection of light from surfaces.
