Fringe width
WebApr 6, 2024 · If the first dark fringe appears at an angle 30°, find the slit width. Solution: Using the diffraction formula for a single slit of width a, the nth dark fringe occurs for, a sin. θ. = nλ. At angle θ=30°, the first dark fringe is located. Using n=1 and. λ = 700 nm=700 X 10⁻⁹m, a sin 30°=1 X 700 X 10⁻⁹m. WebSep 12, 2024 · The Michelson interferometer (invented by the American physicist Albert A. Michelson, 1852–1931) is a precision instrument that produces interference fringes by splitting a light beam into two parts and then recombining them after they have traveled different optical paths. Figure 3.6. 1 depicts the interferometer and the path of a light …
