A slit 0.360mm wide is illuminated by parallel rays of light that have a wavelength of 540nm. The diffraction pattern is observed on a screen that is 1.20 m from the alit. The intensity at the center of the central maximum (θ = 0o) is I0,
(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 bas fallen to I0/2? (See Problem 36.53, part (a), for a hint about how to solve for the phase angle β)
