Question 1 2 pts When we talk about the frequency of an EM wave, what are we really talking about? Select all the correct options. o The time it takes the E-field in the wave to go from zero, reverse direction, then go back to zero. o The number of times each second the E-field in the wave increases from zero, goes back to zero, increases in the reverse direction, and goes back to zero again. o The number of times each second the B-field in the wave increases from zero and goes back to zero. o The time it takes the B-field in the wave to go from zero, reverse direction, then go back to zero. o The number of times each second the B-field in the wave increases from zero, goes back to zero, increases in the reverse direction, and goes back to zero again. o The number of times each second the E-field in the wave increases from zero and goes back to zero.

Explanation / Answer

frequency means the number of times a wave oscillates in one second

so it would be the number of times a value increases from zero to a maximum value ,then to zero and then it again increases to maximum value in the reverse direction and again becomes zero

so the answers would be 2 and 5 options
