Questions and Answers

What is the purpose of using rays in optics?

  • To model the propagation of light through an optical system (correct)
  • To analyze wavefronts of actual light
  • To compute refractive index changes
  • To describe wave phenomena such as diffraction
  • In which circumstances can interference be modeled using the ray model?

  • In all circumstances by adjusting the refractive index
  • In all circumstances by altering the light's wavelength
  • In homogeneous media by changing the wavefronts
  • In limited circumstances by adding phase to the ray model (correct)
  • What happens to light rays in homogeneous media?

  • They curve in a medium with changing refractive index
  • They bend at interfaces
  • They become parallel to wavefronts
  • They are straight (correct)
