Question

Name: Score Feradiry's Law by David Michaels Lab 12 Instructor's Initials: Activity 12.4 Riding the EM E4 s an electromagnetio wave, EM wave. The EM wave has a foe particuler proporties. The ight a transvs both oscilate perpendicularly to the dreaction of propagation, makina ) How does the direction of E relate to the direction of B7 2) How is the magnitude of E related to the magnitude of B? Find an equation 3) What is the value in Sl unita for the speed of light? 4) What is roughly the frequency in hHe) between successive values of tEx or visible light? What about for Bmax? Express your answer as an order of magritude. 5) Which is more energetic red or violet light? Recall from the activities in which you learned ut waves, that the frequency and energy of a wave are determined by the source of an EM creating the red light or the violet light are moving more tr and of violet light? about waves wave are electrons oscillating in SHM, then explain whether the electrons frequently. What is a frequency of red red light ha a frigmey os 400-4H2 6) Use Wien's Law Pmax- (2.898 x10-3 m-KVTI to determine at your body temperature, what is the peak EM wavelength being emitted from you (where in the electromagnetic spectrum is this?) and at what frequency would an average charge be vibrating to emit this light?
