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

Options

  1. AThe velocity of light does not change after reflection
  2. BLight travels in a straight line
  3. CThe velocity of light in air is greater than in glass
  4. DThe velocity of light changes after refraction

Correct answer

C. The velocity of light in air is greater than in glass

Step-by-step solution

According to Newton's corpuscular theory of light, light consists of tiny, perfectly elastic particles called corpuscles that travel in straight lines. During reflection, the corpuscles undergo perfectly elastic collisions with the reflecting surface, meaning their speed remains unchanged. To explain refraction, the theory assumes that corpuscles experience an attractive force when approaching a denser medium. This attractive force increases the normal component of their velocity, leading to the conclusion that the
