A plane electromagnetic wave moving in a vacuum in the -z direction has an electric field described by the expression E=(3300 V / m)sin[(2.50x10ʻ 7(m"))z+@f]-i) ,here z is in meters and tis in 9. seconds. a. What is the wavelength, 1, of this wave? b. What is the frequency, ƒ , of this wave? The B can be written as B = B_ sin(k z+ ot)U where the blank is a +/- sign and a unit vector: i j, or k. What is the correct sign and unit vector for B (note that B is a positive quantity)? d. What is the value of the magnetic field amplitude, B. ? C.
