A laser produces light with a vacuum wavelength of 1550 nm. The laser light is guided to a fiber optic cable, where the wavelength is 1084 nm. How long would it take this light signal to traverse a transatlantic fiber optic cable which is 2680 miles long?

The maximum electric field due to a hemispherically broadcasting radio transmitter is measured to be 777 mV/m at a distance of 9.39 miles from the transmitter. The transmitter, which is 87.9% efficient in its use of electricity, runs 24 hours per day, and the broadcast company pays 13.7 cents per KWHR in electric cost. Calculate: a) the input power of the transmitter b) the annual electric cost to power the transmitter (this will be a large number because it’s a very powerful transmitter and it runs 24/7)
