Two laser beams with different wavelengths, λ1=1064 nm and λ2=600 nm, are incident on a medium. Initially, the phase for both electric fields is zero and the electric fields of both electromagnetic waves are in phase. Consider a right-handed coordinate system. The electromagnetic waves propagate in the positive direction of the OY axis. The electric field corresponding to λ1 oscillates in the YZ plane. The electric field corresponding to λ2 is polarized in a plane making an angle of 45° with the YZ plane. Write the expression for the resultant electric and magnetic fields (vector expression).
