Questions and Answers

What is total internal reflection (TIR) in physics?

  • The phenomenon where waves arriving at the interface from one medium to another are refracted into the second medium
  • The phenomenon where waves arriving at the interface from one medium to another are transmitted through the second medium
  • The phenomenon where waves arriving at the interface from one medium to another are absorbed by the second medium
  • The phenomenon where waves arriving at the interface from one medium to another are completely reflected back into the first medium (correct)

    • Which types of waves can undergo total internal reflection?

  • Electromagnetic waves such as light and microwaves, and other types of waves like sound and water waves (correct)
  • Only sound and water waves
  • Only electromagnetic waves such as light and microwaves
  • Only light waves

    • In a medium with properties independent of direction, what are the 'rays' perpendicular to?

  • The direction of the wave source
  • The associated wavefronts (correct)
  • The direction of the Earth's magnetic field
  • The direction of the wave propagation

    • When does total internal reflection occur?
