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.
Example 3: For a single slit experiment apparatus like the one described above, determine how far from the central fringe the first order violet (Î» = 350nm) and red (Î» = 700nm) colours will appear if the screen is 10 m away and the slit is 0.050 cm wide.
