Total Internal Reflection (TIR) in Physics

• 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 absorbed by the second medium
• When waves arriving at the interface from one medium to another are completely reflected back into the first medium (correct)
• When waves arriving at the interface from one medium to another are scattered in both media

• When waves are incident at a right angle on the interface and the second medium has a lower wave speed than the first
• When waves are incident at a right angle on the interface and the first medium has a lower wave speed than the second
• When waves are incident at a sufficiently oblique angle on the interface and the first medium has a higher wave speed than the second
• When waves are incident at a sufficiently oblique angle on the interface and the second medium has a higher wave speed than the first (correct)

• The waves undergo total internal reflection
• The angle of refraction is less than the angle of incidence
• There is no change in the angle of refraction compared to the angle of incidence
• The angle of refraction is greater than the angle of incidence (correct)
