Answer 1

yes I have............ optical fibres of devices which are used to transmit light from one place to another optical fibres are very thin fibres of glass. thin layer of quarters is coated on it to prevent the light from external reflection.
will it change from one into another in through these 5 hours then the undergrowth through a chain of total internal reflection and finally emerge from another end.

pls mark this one as the brainliest

The answer of u r question is...

"Give a note on optical fibre ...."

Ans:
Optical fiber typically include a core surrounded by a transparent cladding material with low index of refraction. light is kept in dark or by the phenomenon of total internal reflection which causes the fibre 2to act as waveguide...

There are three types of fibre optical cable commonaly used:singleode,multi mode,p plastic optical fibre... transparent glass which are low light to be guided from one end to the other with minimal loss.....
