15 Questions
What is total internal reflection?
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.
When does total internal reflection occur?
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.
Give an example of total internal reflection.
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.
Does total internal reflection only occur with electromagnetic waves?
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.
How is total internal reflection described in terms of rays?
If the waves are capable of forming a narrow beam, the reflection tends to be described in terms of 'rays' rather than waves.
What is total internal reflection?
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.
When does total internal reflection occur?
Total internal reflection occurs when the second medium has a higher wave speed (i.e., lower refractive index) than the first, and the waves are incident at a sufficiently oblique angle on the interface.
