Total internal reflection happens when the light ray passes through a more dense optical medium to a less dense optical medium.
A mirror of good quality material reflects more than 90 percent of the light that falls on it. And the rest, 10 percent, is absorbed by the mirror. The reflection of all rays of light would require the concept of refraction. For more, let’s start understanding the concept of total internal reflection.
There are two main conditions for the occurrence of total internal reflection of light, they are:
The application of total internal reflection is as follows:
A mirage occurs due to atmospheric refraction. Mainly, an optical illusion is responsible for its occurrence. A mirage occurs at a short distance; it can be on a road or desert and shows the appearance of water.
Why do diamonds shine? Diamonds shine because the critical angle of a diamond is 23 degrees. Thus, when the light ray falls on the diamonds’ faces, the angle of incidence becomes more than the critical angle.
Optical fibers help in telecommunication and are considered to be one of the fastest modes of media transfer. Why so? Because the optical fibers suffer total internal reflection. The angle of incidence becomes greater than the critical angle, making it valuable. Endoscopy also makes use of optical fibers.
There are several total internal reflection examples. Some of them are:
Q. What are total internal reflection examples?
Examples of total internal reflection are the shining diamonds, cracked glassware, mirage, optical fibers, etc.
Q. Why is it called total internal reflection?
Because it has the tendency to occur when it passes from a denser medium to a less dense medium.
Q. What is the application of total internal reflection?
The application of total internal reflection are telescopes, microscopes, binoculars, diamonds, fingerprinting sensors, periscopes, spectroscopes, etc.
Q. What is a total internal reflection in physics?
It is the phenomenon of the light ray traveling through the more optically denser medium to the less optically denser medium.
