Question

1 of 20 Which of the following is a true statement? Electromagnetic waves deliver an oscillating amount of energy to a given area of space each second. Electromagnetic waves deliver a constant amount of energy to a given area of space each second. Electromagnetic waves deliver a steadily decreasing amount of energy to a given area of space each second. Electromagnetic waves do not deliver energy. 2 of 20 A particular electromagnetic wave has a frequency of 5x 1017 Hz. What is the wavelength of the wave? 6 x 10-10 m 3 x 108 m 1.7 x109 nm 1.5 x 1026 m

Explanation / Answer

Electromagnetic waves deliever a constant amount of energy.

wavelength = speed / frequency = 3*10^8 / 5*10^17 = 6*10^-10m

Amplitude will affect the intensity of EM wave

2V = L*( di / dt ) = L*0.8/0.1= L*8

So, L = 2/8= 0.25

so, inductance = 0.25H
