NATURE OF LIGHT AND ELECTROMAGNETIC SPECTRUM
CHAPTER # 15

Q.1: What is Newton’s corpuscular theory of light?

Ans:
This theory which was proposed by Newton is given briefly as under:

  • Light consists of tiny (minute) particles called corpuscles.
  • These corpuscles are emitted from a source of light (like the sun).
  • These corpuscles are traveled in a straight line.
  • When these particles enter the eyes, they create the sensation of sight.
  • Velocity of light in a denser medium is greater.
