#1 B (HT ) An electromagnetic wave is propagating out of 2 " " " the page (in the +2: direction if we're being mathy). The magneticeldversustime graph is shown for the location 2 = 0. (Please notice the use of 10'11 s as the unit for time.) (a.) What is the frequency of this wave? Explain how you determined your answer. 03.) What is the wavelength? Explain how you determined your answer. (c.) On the axes provided, sketch the magnetic-eldversusposition graph for this EM wave at the time t = 2 X 10113. For full points, your graph must show two wavelengths of distance and must use all of the tick marks given. Also, you must label the zaxis on the graph with the appropriate numerical values and explain how you determined the initial value of your graph. BmT) 2
