application of total internal reflection
Answers
Diamonds - Essentially, faces of a diamond are cut in a manner that allows the light entering to fall at a given angle, which in turn results in multiple, total internal reflections at various angles while at the same time remaining within the diamond. This is what results in the spackles.
Fiber Optics - An optic fiber is as thick as human hair. they are composed of fine quality glass or quartz fiber and coated with a thin layer of material with lower refractive index. This has a number of uses, which include fiber optic diagnostic tools, fiber optic cables used in telecommunications as well as in endoscopes where fiber optics are used by physicians to view inside the body.
Reflectors - reflectors are typically fixed on various roads where they are used to indicate bending roads etc. They reflect light from headlights from cars guiding the driver along the path.
