What is total internal reflection (TIR) in physics?
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)
