The 'sparkling' of diamonds is due to the way the diamonds are cut, plus the fact that diamonds have a high index of refraction results in the total internal reflection of light. The high index of refraction means that diamonds have a very small minimum critical angle (recall the diamond to vacuum in the observation table). The minimum critical angle in a diamond is 24.4 degrees. Therefore, a lot of the incident light experiences total internal reflection inside the diamond. A ray of light can reflect several times in the diamond before exiting through the top of the diamond.
Fibre optics is a technology that uses light to transmit information along a glass table. To achieve the light not escaping as it travels through the cable, it must have a small critical angle so that the light entering it will have an angle of incidence greater than the minimum critical angle for this medium.

Working Principle of ofc?
Total Internal Reflection
Why can a laser beam travel through a curled-up optical fiber?
The laser shines through the fiber optic cable because the edge of the inside of the cable can act as a mirror. This is called internal reflection.
What is unsustainable technology?
An unsustainable technology is one which uses non-renewable resources. An example of an unsustainable technology is the internal combustion engine, which relies on non-renewable fossil fuels.
What is the relation between internal resistance and load resistance when current is constant in the circute?
The total resistance of a circuit is the sum of the supply's internal resistance and its load resistance, because they are in series with each other. This is true regardless of the magnitude of, or the variation in, the current.
What does the A signify in the thread call out of 250-20UNC-2A?
A refers to the external thread of a screw or bolt. B means internal thread, specified for nuts and inserts. For example a 2A bolt uses a 2B nut
What uses does total internal reflection have?
balls
What is an example of toal internal reflection?
periscope is an example of total internal reflection.
What are 5 practical uses of total internal reflection?
Optical fibers use total internal reflection to guide light signals for telecommunications and internet connectivity. Reflecting prisms in binoculars and periscopes use total internal reflection to redirect light without losing brightness. Reflecting mirrors in digital projectors use total internal reflection to display images onto a screen. Diamond gemstones sparkle due to total internal reflection within the stone. Some sensors and detectors employ total internal reflection to detect changes in the refractive index or presence of substances.
How will you demonstrate total internal reflection?
you can demonstrate total internal reflection using a light source and glass gratings.
Working Principle of ofc?
Total Internal Reflection
What is the principle on which an endoscopy work?
total internal reflection
Does a diamond shine due to total internal reflection?
yes
What do optical fibers rely on?
Total Internal Reflection
Do concave lenses have total internal reflection?
No, concave lenses do not exhibit total internal reflection. Total internal reflection occurs when light traveling through a medium encounters a boundary with a lower refractive index at an angle greater than the critical angle. Concave lenses are designed to converge light rays, whereas total internal reflection typically occurs at interfaces like air-water or glass-air.
What are the uses of TIR?
TIR stands for Total Internal Reflection and it can be used for means of communications via internet or broadband. Also, it can be used for different kinds of Surgery.
When is total internal reflection used in real life?
Total internal reflection is used in fiber optic communication systems, where light signals are transmitted through optical fibers by reflecting off the inner walls due to total internal reflection. It is also used in prism-based devices like binoculars and periscopes to redirect light and form images. Additionally, total internal reflection is utilized in diamond jewelry to enhance its brilliance and sparkle.
Can total internal reflection occur in iron substances?
Total internal reflection typically occurs in materials with a higher refractive index than air, such as glass or water. Iron, being a metal, has a lower refractive index than air, so total internal reflection is not likely to occur in iron substances.
