Monochromatic light falls on a screen 1.60 m from two slits separated by 2.12 mm. The first- and second-order bright fringes are separated by 0.551 mm. What is the wavelength of the light? nm

beam of monochromatic light is incident on a single slit of width 0.560 mm. A diffraction pattern forms on a wall 1.20 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.36 mm. Calculate the wavelength of the light. nm A helium-neon laser (A = 632.8 nm) is used to calibrate a diffraction grating. If the first-order maximum occurs at 20.1 Degree , what is the spacing between adjacent grooves in the grating? (In this problem, assume that the light is incident normally on the gratings.) pm White light is spread out into its spectral components by a diffraction grating. If the grating has 1 980 grooves per centimeter, at what angle does red light of wavelength 640 nm appear in first order? (Assume that the light is incident normally on the gratings.)

Light of wavelength 575 nm falls on a double slit, and the first bright fringe of the interference pattern is seen at an angle of 13.0° from the central maximum. Find the separation between the slits. μm

Light of wavelength 677 nm passes through a slit 6.30 × 10-6 m wide and falls on a screen that is 2.23 m away. What is the distance on the screen from the center of the central bright fringe to the third dark fringe on either side? Number Units

A thin film of oil (n = 1.26) is located on smooth, wet pavement. When viewed perpendicular to the pavement, the film reflects most strongly red light at 640 nm and reflects no yellow light at 548 nm. How thick is the oil film? nm
