The next two questions pertain to the situation described below. Consider a two-slit interference problem, in which plane-waves of light having a wavelength of 450 nm are incident directly upon two slits. The two slits each have a width of 10 um, and the separation between the slits is 80 um. One of the slits is somewhat opaque, such that much of the light entering it gets absorbed (ignore any change to the light's polarization). A screen is placed very far (10 m) past the slits at normal incidence. At the center of this screen, the intensity from one slit acting alone is 25 uW/m². The intensity from the other, somewhat opaque slit acting alone is only 1 uW/m2 7) Which of the following sketches best represents the intensity pattern that would be observed on the screen when both slits are acting together? mam mm plot 1 plot 2 plot 3 a. plot 1 b. plot 2 c. plot 3 8) The ratio of the intensity of the central maximum of the case where one of the slits is opaque to the case where it is not is equal to a. 0.52 b. 0.6 c. 0.64 d. 0.36 e. 0.4
