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
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.
I think total internal reflection
total internal refraction
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.
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.
Not internal refraction - internal reflection. And yes, that's essential to make fiber optics work.
refraction of light
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.
Nope. It's caused by refraction.
what is the meant by total internal reflection
total internal refraction
I think total internal reflection
This means no refraction occurs i.e. Total internal reflection (all light reflected) occurs
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
reflection, refraction, dispersion and total internal reflection of the sun's rays make rainbows appear.
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.
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.
