After a laser beam passes through two thin parallel slits, the first completely dark fringes occur at ± 19.0 with the original direction of the beam, as viewed on a screen far from the slits. (a) What is the ratio of the distance between the slits to the wavelength of the light illuminating the slits? (b) What is the smallest angle, relative to the original direction of the laser beam, at which the intensity of the light is 1 10 the maximum intensity on the screen?

At what angle (in degrees) is the fifth order maximum for 450nm wavelength blue light falling on double slits separated by 0.0380 mm?
Parallel rays of monochromatic light with wavelength 575 nm illuminate two identical slits and produce an interference pattern on a screen that is 75.0 cm from the slits. The centers of the slits are 0.640 mm apart and the width of each slit is 0.434 mm.
If the intensity at the center of the central maximum is 4.20×10−4 W/m2, what is the intensity at a point on the screen that is 0.850 mm from the center of the central maximum?
How far away from the center of a screen is the third dark fringe formed by laser light of wavelength 540 nm that is incident upon a single rectangular slit? The diffraction pattern forms on a screen located at a distance of 1.05 m from the slit, and the width of the central maximum is 3.9 cm.
