The magnetic field of a wave propagating through a certain nonmagnetic material in the positive y direction has an amplitude of 30 mA/m and a frequency of 10 Hz . If the wave is polarized on the positive z direction and its wavelength is 12.6 meter, find the equation of the instantaneous Electric field. Assume the initial phase is 0. Select one: O a. E(y, t) = –2.4rīcos(10°t – y) V/m O b. E(y, t) = 2400žcos(2710°t – 12.6y) V/m O c. E(y, t) = 2.4nīcos(10°t – y) V/m 12.6 O d. E(z, t) = 2.4ýcos(10°t – 2) mv/m 12.6 O e. E(y, t) = 1.6žcos(t – 2.10°ry) v/m 12.6 O f. E(y, t) = 30zcos(10°t + y) mv/m 27 12.6
