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 diffracted into the second medium and do not reflect back into the first medium
- The phenomenon where waves arriving at the interface from one medium to another are partially refracted into the second medium and partially reflected back into the first medium
- The phenomenon where waves arriving at the interface from one medium to another are not refracted into the second medium, but completely reflected back into the first medium (correct)
- The phenomenon where waves arriving at the interface from one medium to another are absorbed by the second medium and do not reflect back into the first medium
In which scenario does total internal reflection occur?
In which scenario does total internal reflection occur?
- When waves arrive at the interface from one medium to another, and the second medium has a lower wave speed than the first
- When waves arrive at the interface from one medium to another, and the refractive index of the second medium is higher than the first
- When waves arrive at the interface from one medium to another, and the second medium has a higher wave speed than the first (correct)
- When waves arrive at the interface from one medium to another, and the refractive index of the second medium is lower than the first
What happens when waves are refracted from a medium of lower propagation speed to a medium of higher propagation speed?
What happens when waves are refracted from a medium of lower propagation speed to a medium of higher propagation speed?
- The angle of refraction is greater than the angle of incidence (correct)
- The angle of refraction is less than the angle of incidence
- There is no refraction in this scenario
- The angle of refraction is equal to the angle of incidence
