- internal refraction is when the ray of light is refracted, for example in a glass or plastic semicircle, and it's refracted inside the semicircle, notoutside.

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
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.
If angle of incidence equals critical angle what is angle of refraction?
90o. i think there will be no refraction there will be totally internal reflection
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
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.

Rainbow is produced when sunlight falls on drops of rain which of the physical phenomena are responsible for this?
diffusion refraction internal refraction
What is mirage due to total internal reflection?
refraction of light

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
What happens if the refraction angle is greater than ninety degrees?
This means no refraction occurs i.e. Total internal reflection (all light reflected) occurs
When the refracted light is bent back into the incident material is called a?
total internal refraction
What happens when the angle of refraction is 90 degrees or greater?
I think total internal reflection
What is the minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees?
The minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees is 1.414
