The intensity is given by II = + 0 54 c o s φ b g , where I 0 is the intensity that would be produced by the first wave if the second were not present. Since cos cos φφ =− 22 1 2 bg , this may also be written as =+ 0 2 18 2 cos . 121. We take the electric field of one wave, at the screen, to be EE t 10 = sin ω b g and the electric field of the other to be t 20 2 = + , b g where the phase difference is given by φθ = F H G I K J 2 π λ d sin . Here d is the center-to-center slit separation and
