Question

According to corpuscular theory of light, Which is NOT the property of light?

• A. The velocity of light does not change after reflection
• B. Light travels in a straight line
• C. The velocity of light in air is greater than in glass
• D. The velocity of light changes after refraction

Hint:

The corpuscular theory says light is faster in a denser medium, so claiming it is faster in air is not its prediction.

Answer 1

The Correct Option is C

Step 1: Recall the key prediction.
In the corpuscular model, $v_{glass} > v_{air}$.

Step 2: Compare.
Statements (A), (B) and (D) are in line with the particle model. Only (C) reverses the speed order, which belongs to the wave theory.

Final Answer:
Option (C). \[ \boxed{\text{(C)}} \]
