An electromagnetic wave is traveling in a vacuum. at a particular instant for this wave, e-[(-76.0)1+ (95.0)j + (38.0x) n/с, and b-[(0290)1+ (0.200)j + (0.080지 (a) calculate the following quantities. (give your answers, in μτ . nc, to at least three decimal places.) exbx eyby ebz ht -n/c ht -n/c ht -n/c ex3x+ evay+e are the two fields mutually perpendicular? how do you know? yes, because their dot product is not equal to zero yes, because their dot product is equal to zero no, because their dot product is not equal to zero. no, because their dot product is equal to zero 0 (b) determine the component representation of the poynting vector (in w/m) for these fields. 2 w/m
