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

Answer: (c). Newton's corpuscular theory predicts that light travels faster in a denser medium: vglass > vair. It does explain straight-line travel, unchanged speed after reflection and a change of speed on refraction. The statement vair > vglass contradicts the corpuscular theory. So the answer is (c).

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

Show answer and solution

Answer: (c)

Newton's corpuscular theory predicts that light travels faster in a denser medium: $v_{glass} > v_{air}$ .
It does explain straight-line travel, unchanged speed after reflection and a change of speed on refraction.
The statement $v_{air} > v_{glass}$ contradicts the corpuscular theory.
So the answer is (c).
