Assertion Reason Questions on Light: Shadows and Reflections

Assertion Reason Questions

Q1. Assertion (A): The Moon is visible at night because it emits its own light.
Reason (R): The Moon reflects sunlight falling on it.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (c) A is true, but R is false.
Explanation: The Moon does not emit light; it reflects sunlight. So A is false, R is true.

Difficulty: ★★★☆☆ (Moderate)

Q2. Assertion (A): Light passes through transparent objects and forms no shadow.
Reason (R): Transparent objects allow most of the light to pass through them.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: Transparent objects (like glass) transmit nearly all light, so shadows are not formed. R explains A.

Difficulty: ★★☆☆☆ (Easy)

Q3. Assertion (A): Shadows are formed only when the object is luminous.
Reason (R): Shadows are formed when an opaque object blocks the path of light.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (d) A is false and R is true.
Explanation: Shadows require opaque objects, not luminous ones. Hence, A is false.

Difficulty: ★★★★☆ (Challenging)

Q4. Assertion (A): The image formed in a pinhole camera is inverted.
Reason (R): Light travels in a straight line and crosses at the pinhole.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: Due to straight-line travel and pinhole crossing, images appear upside down.

Difficulty: ★★★☆☆ (Moderate)

Q5. Assertion (A): A mirror forms an erect and laterally inverted image.
Reason (R): The reflection of light changes the direction of light at the surface of a mirror.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: Plane mirrors reflect light to create erect but laterally inverted images. R explains A.
