In fiber optics something called total internal reflection occurs... this is where light enters the the glass tube and bounces along the inside. For this to happen there needs to be a coating of a material surrounding the glass fiber which is less dense than the fiber itself. The light has to hit the surface on the inside at a large enough angle for total internal reflection to occur, otherwise the light will leave the fiber. Because of this, the fibers can't bend beyond a certain point. In endoscopy fiber optics are used to direct light from a source into the area of the patients body that's being examined and also as a means of transmitting the image back up to the observer.
The branch of physics that studies light is called optics. Optics involves the behavior and properties of light, including its interactions with materials and its manipulation through lenses, mirrors, and other optical components. This field explores phenomena such as reflection, refraction, diffraction, and polarization of light.

The MKI formula stands for Modified Kramers-Kronig relations in physics and optics, which are used to relate the real and imaginary parts of a complex function.
