In a single-slit experiment, a beam of monochromatic light of wavelength 634 nm passes through a single slit of width 15.8 µm. The diffraction pattern is displayed on a screen that is 2.91 m away. What is the distance between the third dark fringe and the center of the diffraction pattern? Give your answer in cm.

An instructor directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 550 nm and the slit is 0.225 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.20 m from the slit. (a) How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen? mm (b) How wide (in mm) is either of the two first-order bright fringes, as measured on the screen? mm

Monochromatic light of wavelength 622 nm is incident on a single-slit of width 0.321 mm. The diffraction pattern is observed on a screen 4.88 m from the slit. The intensity at the center of the central maximum is I_0. What is the distance (in mm) on the screen from the center of the central maximum to a point on the screen where the intensity has fallen to I_0/2?

Monochromatic light of wavelength 461 nm from a distant source passes through a slit that is 0.0310 mm wide. In the resulting diffraction pattern, the intensity at the center of the central maximum (θ = 0o) is 1.00×10−4 W/m^2. What is the intensity at a point on the screen that corresponds to θ = 1.20o?
