I just need question C. Im honestly completely lost. Thank you so so so much!

B(MT) #1 An electromagnetic wave is propagating out of 2 the page (in the + z direction if we're being mathy). The magnetic-field-versus-time graph t(10-1 s) is shown for the location z = 0. (Please notice . ..... .NO.+ . . . . .OR the use of 10-1 s as the unit for time.), :. . . . . .. S = T ma KAB of wavelength period 72 4 x18 15- 132.5*10 (a.) What is the frequency of this wave? Explain how you determined your answer. wavelength = C 2.5 x 1010 Hz 3 *10 f (b.) What is the wavelength? Explain how you determined your answer. 2. 5x 10 0 = 1.2x10-2 0. 0/2m is the warelens in (c. ) On the axes provided, sketch the magnetic-field-versus-position graph for this EM wave at the time t = 2 x 10-Us. 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 z-axis on the graph with the appropriate numerical values and explain how you determined the initial value of your graph. B(MT) 2 Z -2
