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)

Which types of waves can undergo total internal reflection?

Electromagnetic waves such as light and microwaves, and other types of waves like sound and water waves (correct)

Only sound and water waves

Only electromagnetic waves such as light and microwaves

Only light waves

In a medium with properties independent of direction, what are the 'rays' perpendicular to?

The direction of the wave source

The associated wavefronts (correct)

The direction of the Earth's magnetic field

The direction of the wave propagation

When does total internal reflection occur?
