Benzyl chloride. Benzyl chloride, or Î±-chlorotoluene, is an organic compound with the formula C6H5CH2Cl. This colourless liquid is a reactive organochlorine compound that is a widely used chemical building block.
Two slits are illuminated with red light (Î» = 650 nm). The slits are 0.25 mm apart and the distance to the screen is 1.25 m. What fraction of the maximum intensity on the screen is the intensity measured at a distance 3.0 mm from the central.
As a start, set the wavelength at Î» = 656nm (Red) and d = 3600 n m, slits separation. (This means that d = 0. 0036 m m, a very small separation between the slits). You should get 5 fringes on each side of the central fringe.
