Could use some help thanks

PREVIOUS ANSWERS ASK YOUR TEACHER PRACTICE ANOTHER The magnetic field in a plane electromagnetic wave is represented by the equation B = Bmax sin(ky - ct)i where Bmax = 6.30 x 10 T and k = 5.62 x 10' /m. (Assume a standard xyz right-handed coordinate system.) (a) What is the magnitude and direction of the electric field at the instant the magnetic field is a maximum? (Express your answer in vector form.) Emax X For a plane electromagnetic wave, how are the amplitudes of the electric and magnetic fields related? What is the direction of propagation of the wave in this case? Review the right-hand rule for vector product of the electric and magnetic field vectors. V/m (b) What is the wavelength of the wave? 112 nm (c) What is the frequency of the wave? 2.68e+15 Hz Additional Materials Reading
