Why amplitude modulation used for long distances?
AM travels well over longer distances than FM is capable of, but has a lower fidelity and is more susceptible to metal, which is why it is not used as often in cities.
What happens to the electrical energy when power is transmitted through long distances?
Because wires are not perfect conductors, energy is released as heat. This is why electricity is transmitted at very high voltage and low current to reduce energy loss.
How long does it take electricity to travel from New York to Los Angeles?
Electricity travels in a vacuum at aprox. 186,000 miles per second. Now do the math!
What nm of light travels long distances?
Red light, in the region of 650 to 700 nm, travels further than blue.
