A single slit that is 2100 nm wide forms a diffraction pattern when illuminated by monochromatic light of 680-nm wavelength. At an angle of 10° from the central maximum, what is the ratio of the intensity to the intensity of the central maximum? 1/10=0.35 1/10=0.39 1/10=0.43 1/10=0.47

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

The distance between two slits is 1.50 × 10 -5 m. A beam of coherent light of wavelength 600 nm illuminates these slits, and the distance between the slit and the screen is 2.00 m. What is the distance on the screen between the central bright fringe and the fourth-order bright fringe? 0.201 m 0.324 m 0.132 m 0.528 m 0.688 m

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?
