Assertion (A): Optical fibres are widely used in communication network.Reason (R) Optical fibres are small in size, light weight, flexible and there is no scope for interference in them.
- A Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of (A)
- B Both \((A)\) and \((R)\) are true but \((R)\) is not the correct explanation of (A)
- C \((A)\) is true but \((R)\) is false
- D \((A)\) is false but \((R)\) is true
Answer & Solution
Correct Answer
(C) \((A)\) is true but \((R)\) is false
Step-by-step Solution
Detailed explanation
In optical communication, light is transmitted in form of light pulses along an optical fibre as transmission medium. Since wavelength of light is very small as compared to the radio waves, it provides a very large band width and can carry a huge amount of information. In…
