Applications of Total Internal Reflection in Nature

Topic Content:

Mirage:

This usually occur on a sunny day along the road which shows that there is a pool of water ahead of a driver, even though it is an optical illusion because the driver never meets the water.  This usually occurs due to total internal reflection at the boundary of hot and colder air.

Totally Reflecting Prism:

A right angle isosceles prism can reflect entire light throughout the prism as rays of light entering any of the faces are greater than the critical angle, hence it is totally reflected.

Prismatic Binoculars:

These are optical instruments used to provide a magnified stereoscopic view of distant objects. A prism binocular employs a combination of right-angled isosceles prisms to achieve a high magnification without being as long as a telescope.

Optical Fibre:

These are used to transmit light
