1.	Identify the range of optical communication from the following.(a) Visible to ultraviolet(b) Microwaves to ultraviolet(c) Microwaves to x rays(d) X rays to gamma raysThis question was posed to me in semester exam.This intriguing question originated from Communication Systems in chapter Communication Systems of Physics – Class 12
Answer» Right choice is (b) MICROWAVES to ultraviolet Easiest EXPLANATION: OPTICAL communication which is also called optical telecommunication is referring to a type of communication at a distance USING light to carry information. Optical communication using fibers is PERFORMED in the frequency range of 1 THz to 1000 THz, i.e. microwaves to ultraviolet.
