Questions and Answers

What is total internal reflection (TIR)?

  • When waves arriving at the interface from one medium to another are scattered in all directions
  • When waves arriving at the interface from one medium to another are absorbed by the second medium
  • When waves arriving at the interface from one medium to another are refracted into the second medium
  • When waves arriving at the interface from one medium to another are completely reflected back into the first medium (correct)
  • In which scenario does total internal reflection occur?

  • When the refractive index of the second medium is higher than the first and the waves are incident at a sufficiently oblique angle on the interface
  • When the second medium has a higher wave speed than the first and the waves are incident at a sufficiently oblique angle on the interface (correct)
  • When the second medium has a lower wave speed than the first and the waves are incident at a perpendicular angle on the interface
  • When the refractive index of the second medium is lower than the first and the waves are incident at a perpendicular angle on the interface
  • Which types of waves can undergo total internal reflection?

  • Electromagnetic waves, sound waves, and water waves (correct)
  • Light waves, radio waves, and seismic waves
  • Electromagnetic waves, seismic waves, and wind waves
  • Sound waves, radio waves, and ocean waves
  • How is total internal reflection described when waves are capable of forming a narrow beam?
