What is total internal reflection (TIR)?
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?
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
