what is total internal reflection definition Total internal reflection in physics complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium This occurs if the angle of incidence is greater
Total internal reflection allows light to be contained and guided along very thin fibres Usually made of glass these are called optical fibres and they have many uses Definition What is Total Internal Reflection Total internal reflection TIR is the phenomenon in which a ray of light traveling from a denser medium to a rarer medium is reflected in the denser medium at the interface between the two media

In physics total internal reflection TIR is the phenomenon in which waves arriving at the interface boundary from one medium to another e g from water to air are not refracted into the second external medium but completely reflected back into the first internal medium Total internal reflection is a phenomenon that occurs at the boundary between two mediums such that if the incident angle in the first medium is greater than the critical angle then all the light is reflected back into that medium
Total internal reflection or TIR as it is intimately called is the reflection of the total amount of incident light at the boundary between two media TIR is the topic of focus in Lesson 3 To understand total internal reflection we will begin with a thought experiment Total internal reflection coupled with a large index of refraction explains why diamonds sparkle more than other materials The critical angle for a diamond to air surface is only 24 4 so when light enters a diamond it has trouble getting back out Figure PageIndex 6

Total Internal Reflection When light is incident upon a medium of lesser index of refraction the ray is bent away from the normal so the exit angle is greater than the incident angle Such reflection is commonly called internal reflection Explain the phenomenon of total internal reflection Describe the workings and uses of fiber optics Analyze the reason for the sparkle of diamonds A good quality mirror may reflect more than 90 of the light that falls on it absorbing the rest But it would be useful to have a mirror that reflects all of the light that falls on it
