Question

**a.) When using a diffraction grating with a given slit
density, usually given as slits or lines per mm, how do you
calculate the slit separation between adjacent slits?**

**b.) The energy levels predicted by the Bohr model in the
hydrogen atom were given by the following expression:**

**E _{n} = - 13.6eV / n^{2}**

**Draw an energy level diagram from n = 1 to n = 6
labeling each level with its corresponding energy (Ground level to
Excited level)****. Describe how the spacings between
adjacent energy levels changes with increasing n
values.**

Answer #1

A diffraction grating is made up of slits of width a with
separation d. The grating is illuminated by monochromatic plane
waves of wavelength ? at normal incidence. What is the angular
width of a spectral line observed in the first order if the grating
has N slits? State your answer in terms of the given variables. ??w
