Question

Fiber optic communication enables higher data rates than electrical cables because light travels faster than radio waves. True or false?

Answer 1

Ans:

False

Reason:

fiber optic communication is made of light. There will be very little loss of signal during transmission by light in fiber optics. So the data can move at higher speeds and greater distances.

But in electrical cables, while transmitting by radio waves, due to interaction fo radio waves with the material of the cable, there is loss of signal during transmission. So the data moves at lower speeds in electrical cables when compared with fiber optics.

Speed of radio waves and light are same . Interaction of these waves with different material will define the data rates.
