WebFinal answer. Light of wavelength 42.6 nm (in vacuum) is incident on a diffraction grating that has a slit separation of 1.2×10−5 m. The distance between the grating and the viewing screen is 0.18 m. A diffraction pattern is produced on the screen that consists of a central bright fringe and higher-order bright fringes (see the drawing). WebWhen passing white light through a diffraction grating, the central bright fringe appears _____. as a rainbow as white light dark None of the above 17. The number of lines per millimeter of a reflection diffraction grating can be calculated using the same formula as for the transmission diffraction grating. True False 18.
WebMar 6, 2024 · The fringes are visible only in the common part of the two beams. By neglecting the distance between the slits, the angular width associated with the … WebFor the first fringe, Δ L = λ 2 = a 2 sin θ λ = a sin θ For a ray emanating from any point in the slit, there exists another ray at a distance of a/2 that can cause destructive interference. Thus, at θ = sin−1λa, there is …
WebFringe width is the distance between two consecutive bright spots (maximas, where constructive interference take place) or two consecutive dark spots (minimas, where …
WebIf the fringes are measured in the water, the fringe width will be narrower, because, in water, the wavelength of light is less. Thus, the fringe will decrease.
