MCQ
Corpuscular theory of light was advanced by:
  • A
    Huygen
  • B
    Newton
  • C
    Maxwell
  • D
    Hertz

Answer

  1. Newton

Explanation:

The corpuscular theory was largely developed by Sir Isaac newton. Newton's theory remained in force for more than 100 years and took precedence over Huygen's wave front theory, partly because of Newton’s great prestige.

When the corpuscular theory failed to adequately explain the diffraction, interference and polarization of light it was abandoned in favour of Huygens' wave theory.
