2. An electromagnetic wave hits a student (in air) who measures a maximum electric field of E = (6.00 -10ʻV/m)( – 2ŷ – 2)/ /6 and finds that the magnetic field is in the &+ ŷ – 2 direction. The light has a wavelength of 700 nm. (a) Find the two possible propagation vectors? K 27 Sk = 6.9 x105 m 700y1097 or ho here V. (b) Find the angular frequency? untime (c) Find the amplitude of the magnetic field? (6x10"Vm) here too (d) Write down two different possible arguments of the wave phase factor [x is the argument of f(x)].
