Relation between intensity and width of slits
WebFraunhofer diffraction due to single slit: Consider a narrow slit AB of width ‘a’, kept perpendicular to the plane of the paper. The slit can be imagined to be divided into extremely thin slits or slit elements. It is illuminated by a parallel beam of monochromatic light of wavelength λ i.e., a plane wavefront is an incident on AB. WebAboutTranscript. Fringe width is the distance between two consecutive bright spots (maximas, where constructive interference take place) or two consecutive dark spots (minimas, where destructive interference take place). Let's derive an expression for the linear and angular fringe width. Created by Mahesh Shenoy.

WebSlits are available in a wide range of widths, ranging from 5 µm up to a maximum of 800 µm, and are typically between 1 mm and 2 mm in height, with a 1 mm height being the standard. The slit must be placed very accurately within the optical path of the spectrometer due to its very small size, otherwise the optical power throughput and the ... Weba = width of the slits and. b = distance between slits. The quantity (a+b) represents the grating constant or the reciprocal of (N) number of lines ruled per centimeter of the grating. i.e. ( a + b) = 1 N ( lines/cm) Thus, out of the given option, option- 2 is the correct answer. Diffraction of light is an optical phenomenon in which the light ...
