Questions and Answers

Which of the following best describes total internal reflection of light?

  • The reflection of light at an angle greater than the critical angle when it encounters a boundary between two media (correct)
  • The scattering of light in all directions when it encounters an uneven surface
  • The reflection of light off a smooth surface at the same angle it hits the surface
  • The bending of light as it passes through a medium with different refractive indices
  • What happens to light when it undergoes total internal reflection?

  • It is reflected back into the same medium at an angle greater than the critical angle (correct)
  • It is transmitted through the medium
  • It is reflected off the medium at the same angle it hits the medium
  • It is absorbed by the medium
  • Under what conditions does total internal reflection occur?

  • When light encounters a boundary between two media and the angle of incidence is greater than the critical angle (correct)
  • When light encounters a boundary between two media and the angle of incidence is less than the critical angle
  • When light passes from a medium with a lower refractive index to a medium with a higher refractive index
  • When light passes from a medium with a higher refractive index to a medium with a lower refractive index
