Total Internal Reflection (TIR)

Total internal reflection is the phenomenon in which 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.

Total internal reflection occurs when the second medium has a higher wave speed than the first, and the waves are incident at a sufficiently oblique angle on the interface.

A typical example of total internal reflection is when the water-to-air surface in a fish tank reflects the underwater scene like a mirror when viewed obliquely from below.

<p>No, total internal reflection can occur not only with electromagnetic waves such as light and microwaves, but also with other types of waves, including sound and water waves.</p> Signup and view all the answers
