Question

Microwave communication is preferred over optical communication. Microwaves provide large number of channels and bandwidth compared to optical signals.

• A. if both assertion and reason are true and the reason is the correct explanation of the assertion
• B. if both assertion and reason are true and the reason is not the correct explanation of the assertion
• C. if assertion is true but reason is false
• D. if both assertion and reason are false statements

Answer 1

Answer: (D)

if both assertion and reason are false statements

Answer 2

Microwaves are electromagnetic waves with wavelength as longer than those of infrared light but relatively short from radio waves. The microwave range includes ultra high frequency $(0.3 - 3 \,GHz)$, super high frequency $(3 - 30 \,GHz)$ and extremely high frequency $(30 - 300\, GHz)$ signals. While optical communication is any form of telecommunication that uses light as the transmission medium. Hence, its channels and bandwidth are lesser than microwave communication
