Application of TIR Mirage effect:- caused by refraction of light through a layer of air with varying temperature Optical fibre communication:- transmission of data as light signals through thin flexible fibers Sparkling of diamond:- which traps and reflect light multiple times within the diamond

[@HariomKumar-d1v2l]

Optical fibres are extensively used for transmitting audio and video signal through long distance.

[@HariomKumar-d1v2l]

Sparkling of diamond: the critical angle for diamond_air interface is very small, therefore on light enters a diamond, it is very likely to undergo total internal reflection inside it.

[@HariomKumar-d1v2l]

Mirage effect: it is the phenomenon, in which an inverted image of distant tall objects cause an optical illusion of water.

Maximum scattering colour is violet

World ka largest telescope America ma hai❤

[@AdarshKumar-e4e]

World largest telescope America me hai

[@HariomKumar-d1v2l]

The largest telescope in India is in kavalur ,Tamil Nadu. The largest reflecting telescopes in the world are the pair of keck telescopes in Hawaii,USA.

Convex lens - converging Concave lens - diverging

[@HariomKumar-d1v2l]

Power of accommodation is the ability of the eye lens to focus near and far object clearly on the retina by adjusting its focal length.

A defect in the eye in which a person can see near objects clearly and distant objects blurred is called nearsightedness. A defect in the eye in which a person can see distant objects clearly and nearby objects blurred is called farsightedness.
