Question
Total internal reflection occurs only when light travels from
Solution
Total internal reflection occurs only when light travels from a medium with a higher refractive index to a medium with a lower refractive index.
Here are the steps:
-
Light is traveling from a medium of higher refractive index (like water or glass) to a medium of lower refractive index (like air).
-
The light hits the boundary between the two mediums at an angle greater than the so-called critical angle. The critical angle is the angle of incidence that provides an angle of refraction of 90-degrees.
-
Instead of refracting or bending away from the normal (the line perpendicular to the boundary), the light reflects back into the medium with the higher refractive index.
-
This phenomenon, where the light is completely reflected back into the denser medium, is known as total internal reflection.
This is the principle behind fiber optics and the brilliance of diamonds.
