Questions and Answers

What is a ray in optics?

  • A physical beam of light
  • An idealized geometrical model of light or other electromagnetic radiation (correct)
  • A representation of diffraction phenomena

  • How are rays used to model the propagation of light through an optical system?

  • By applying diffraction phenomena to the ray model
  • By dividing the real light field into discrete rays for computational propagation (correct)
  • By using wavefronts to simulate light propagation
