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.
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 does refraction and reflection have to do with mirages?
Actually it is refraction process and specifically indentified as total internal reflection. The condition for total reflection is that the ray has to traverse from denser medium to the rarer medium and the angle of incidence has to be more than the critical angle.
What is internal refraction?
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.
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 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
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 happens if the refraction angle is greater than ninety degrees?
This means no refraction occurs i.e. Total internal reflection (all light reflected) occurs
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
Where do rainbows appear?
reflection, refraction, dispersion and total internal reflection of the sun's rays make rainbows appear.
What does refraction and reflection have to do with mirages?

Caused by light refraction in the atmosphere?
Mirage is a good example which is seen due to refraction of light and especially due to total internal reflection. ============================ A semi-opposing opinion: No reflection is required for the creation of a mirage, only refraction. ============================= Hope you might have heard about the conditions for total internal relection to take place. 1) Ray has to traverse from denser to rarer 2) the angle of incidence is to be more than critical angle of the denser medium So in such a case the refraction phenomenon cannot take place and so all the energy to be refracted is sent back to the denser medium itself. Hence named as total internal reflection. Of course total internal reflection is totally different from ordinary reflection.
