A 475 nm wavelength spectral line is actually a doublet, 0.0043 nm separation. (a) What is the smallest number of lines that a diffraction network needs to have to separate this doublet in the 2nd order spectrum? (b) If this network is 10 cm long, in what direction will the line be observed in this spectrum? What will be the angular separation between the two components?
In a double-slit experiment, the fourth
maximum ( m = 4) is 2.8 cm from the central
maximum on a screen that is 1.4 m away from
the slits. If the wavelength of light being used
is 560 nm, what is the spacing between the
two slits in mm?

Answer:
Coherent light is passed through two narrow slits whose separation is 20.0 mm. The second-order bright fringe in the interference pattern is located at an angle of 0.0300 rad. If electrons are used instead of light, what must the kinetic energy (in electron volts) of the electrons be if they are to produce an interference pattern for which the second-order maximum is also at 0.0300 rad?
