The intensity is given by II=+054cosφbg, where I0is the intensity that would be produced by the first wave if the second were not present. Since coscosφφ=−2212bg, this may also be written as =+02182cos. 121. We take the electric field of one wave, at the screen, to be EEt10=sinωbgand the electric field of the other to be t202=+,bgwhere the phase difference is given by φθ=FHGIKJ2πλdsin .Here dis the center-to-center slit separation and
