Question: Slit 1 of a double slit is wider than slit 2, so that the light from 1 has amplitude 3.00 times that of the light

Slit 1 of a double slit is wider than slit 2, so that the light from 1 has amplitude 3.00 times that of the light from 2. Show that for this situation, Equation 37.11 is replaced by the equation I = (4Imax/9) (1 + 3 cos2 ǿ/2).
