Frustrated total internal reflection, or '''FITR''', is a phenomenon that occurs when electromagnetic waves reflected within an optical medium(with a lower index of refraction) are interrupted in their internal reflection by an object with a higher refractive index.

In a typical optical system, total internal reflection occurs when a light ray reflects completely inside higher-index medium and reflects onto a lower-index surface.
'''Frustrated total internal reflection''', or '''FTIR''', is a phenomenon that occurs when electromagnetic waves reflected within an optical medium (with a lower index of refraction) are interrupted in their internal reflection by an object with a higher refractive index.


The optical properties of light can be generally identified through four categories:
In a typical optical system, total internal reflection occurs when a light ray inside a higher-index medium reflects completely at a boundary between the medium and a second, lower-index medium.


* refraction

* reflection

* interference
* diffraction
 
Refraction occurs when a the speed of a light wave changes as it enters a slower medium.  The amount of refraction is determined by the index of refraction between the two different media.

Frustrated total internal reflection, or FTIR, is a phenomenon that occurs when electromagnetic waves reflected within an optical medium (with a lower index of refraction) are interrupted in their internal reflection by an object with a higher refractive index.

In a typical optical system, total internal reflection occurs when a light ray inside a higher-index medium reflects completely at a boundary between the medium and a second, lower-index medium.
