$36\mathrm{.}52$ A slit $0\mathrm{.}360$ mm wide is illuminated by parallel rays of light that have a wavelength of $540$ nm$.$ The diffraction pattern is observed on a screen that is $1\mathrm{.}20$ m from the slit. The intensity at the center of the central maximum is $($a$)$ What is the distance on the screen from the center of the central maximum to the first minimum? $($b$)$ What is the distance on the screen from the center of the central maximum to the point where the intensity has fallen to
