Two laser beams with wavelengths λ1=596 nm and λ;2=574 nm are aimed at the same point. The electric field from each laser in the y-direction behaves as the function, Ei,y(x,t)=A(sin2πfit−2πxλi) for i=1 or 2, and they propagate at a speed of light c. Both fields have the same amplitude, A=1 N/C. Find the value of the total electric field in the y-direction Ey, in newtons per coulomb, at a time of exactly one femtosecond (10−15 seconds) if the position the lasers is aimed at is exactly 100 nanometers away from each laser.
