Red laser light of wavelength 700 nm travels through vacuum in the +z direction. At some instant of time the magnetic field of this wave points in the -y direction at point P. What is the direction of the electric field of this wave at the same time but at a point 700 nm beyond point P in the +z direction? Select one: a. +z b. -x c. -z d. +x e. +y f. -y
