What is total internal reflection (TIR) in physics?
What is total internal reflection (TIR) in physics?
- 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 scattered in all directions
- 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)
Under what conditions does total internal reflection occur?
Under what conditions does total internal reflection occur?
- When the second medium has a higher wave speed and the waves are incident at a sufficiently oblique angle on the interface (correct)
- When the first medium has a lower wave speed and the waves are incident at a perpendicular angle on the interface
- When the first medium has a higher wave speed and the waves are incident at a sufficiently oblique angle on the interface
- When the second medium has a lower wave speed and the waves are incident at a perpendicular angle on the interface
In what situations does total internal reflection occur?
In what situations does total internal reflection occur?
- With electromagnetic waves such as light and microwaves, and also with other types of waves including sound and water waves (correct)
- Only with light waves
- Only with electromagnetic waves such as light and microwaves
- Only with sound and water waves
