Applications of Total Internal Reflection
- Optical fibres use total internal reflection. An optical fibre is made up of an inner core made of glass with a high refractive index and an outer cladding made of glass with a lower refractive index.
- An instrument made of fibre optic wire is called an endoscope. Doctors use it to view the interior of the human body, including the stomach and duodenum.
- In the telephone system, fibre optic cables have now replaced copper cables in telecommunications. Multiple signals can be transmitted quickly across fibre bundles using laser-generated light bursts.
Total Internal Reflection
In Physics, total internal reflection is the complete reflection of a light ray within the medium (air, water glass, etc). For example, the total internal reflection of rays of light takes place in a Diamond. Since Dimond has multiple reflecting surfaces through which the Total internal reflection takes place. The total internal reflection occurs when light travels from a denser medium to a less dense medium and the angle of incidence must be greater than the critical angle. The phenomenon of total internal reflection has a wide application in optical devices such as telescopes, binoculars, periscopes, etc. Read more about the concepts of Total Internal Reflection like Total Internal Reflection of Light, definition, critical angle, and total internal reflection, examples, and FAQs, here in this article!
