Do you need total internal refraction to get the fiber optics to work?

Not internal refraction - internal reflection. And yes, that's essential to make fiber optics work.

What is the physics behind the fiber optics in endoscopy how does it function?
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.
What is total internal refraction?
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
In fiber optic cables what reflects the light back into the core?
This is done by total internal reflection. It is the result of the fact that the inner glass and the outer glass have different indices of refraction (the outside glass has a lower index of refraction).
When is total internal reflection used for carrying images?
Total internal reflection is used in fiber optics to transmit data - usually as ones and zeroes. This data can represent any type of information - text, voice, images, video, executable programs, etc.
What is mirage due to total internal reflection?
refraction of light
When does total internal refraction happen?
Total internal refraction happens when a light ray travel from a lighter medium to a denser medium. Ex. A light ray passing through a Prism.

Is total internal reflection causes rainbow?
Nope. It's caused by refraction.
What is refraction of light and what cause light to refract?
what is the meant by total internal reflection
How a scratch outside of an optical fiber might cause problems?
Fiber optics, using optical fiber, are specially designed to implement total internal reflection. A signal passed from one end of the fiber to the other end of the fiber is a single beam of light that repeatedly bounces off the edges of the fiber until it reaches it's destination. By scratching the outside of an optical fiber, this property can be disrupted causing the signal to be lost.
What happens when the angle of refraction is 90 degrees or greater?
I think total internal reflection
When the refracted light is bent back into the incident material is called a?
total internal refraction
