In general, to keep it from getting out. Although, this sounds like there is more specific information prepended to it. Like: which system; what is being reflected (energy or matter);
is it assuming an enclosure; why do I want to keep it in...?
Fiber optics find internal reflection useful for keeping data intact and lossless, lasers like some internal reflection for decreased power consumption during the excitation process, coal miners find it useful for keeping the marbles in the tunnel when they knock the loose stuff down from the ceiling, perhaps a discussion thread can come up with other uses.
What else can I help you with?
What is an example of toal internal reflection?
periscope is an example of total internal reflection.
How will you demonstrate total internal reflection?
you can demonstrate total internal reflection using a light source and glass gratings.
Do you need total internal refraction to get the fiber optics to work?
Not internal refraction - internal reflection. And yes, that's essential to make fiber optics work.
What uses does total internal reflection have?
balls
What is 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?
The minimum index of refraction for total internal reflection at a 45-degree angle is 1.41. This means that the glass or plastic prism would need to have an index of refraction greater than or equal to 1.41 to achieve total internal reflection at that angle.
What are the disadvantages of total internal reflection?
Some disadvantages of total internal reflection include the need for specific angle and material requirements, limited applications in certain situations, and the potential for signal loss due to factors like imperfections in the material or surface roughness.
Working Principle of ofc?
Total Internal Reflection
What is the principle on which an endoscopy work?
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.
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.
Does a diamond shine due to total internal reflection?
yes
What do optical fibers rely on?
