A light source shines light consisting of two wavelengths, λ1 = 540 nm (green) and λ2 = 450 nm (blue), on two slits separated by 0.170 mm. The two overlapping interference patterns, one from each wavelength, are observed on a screen 1.31 m from the slits. What is the minimum distance (in cm) from the center of the screen to a point where a bright fringe of the green light coincides with a bright fringe of the blue light?

Light consisting of a mixture of two different wavelengths falls on a two-slit interference apparatus. The centers of the slits are 0.100 mm apart. After passing through the slits, the light falls on a screen 5.00 m from the slits. For each of the two colors, the middle of the bright spot nearest to the central bright spot is at the following distance from the middle of the central bright spot: 2.4 cm; 3.3 cm.

Monochromatic light of wavelength λ1 is sent through two closely-spaced slits separated by a distance d1 = 1.8 mm. A resulting interference pattern is shown on a screen L1 away. Another monochromatic light source, this one of wavelength λ2, is sent through a diffraction grating toward the same screen, resulting in a second interference pattern. The diffraction grating is a distance L2 from the screen and has 400 lines per mm etched onto it. A) Assume that L1 = L2...

consider now interference of light as it passes through a transmission grating with N slits with a separation h. The light is composed of two wavelengths, λ1 = 500 nm and λ2 = 600 nm. The two wavelengths lead to two interference patterns on a screen. Some of the interference peaks from the 500 nm light overlap with some interference peaks originating from the 600 nm light. Calculate which interference peaks of the two colors overlap, up to an interference...
