Assignment Help Physics

Reference no: EM13661573

a) Find the resolving power of a grating needed to separate the sodium-D spectral lines, which are at 588.5 nm and 589.2 nm.

b) How many lines should the grating have to achieve this resolution in first order? (This is a very lower solution in terms of present-day spectroscopic standards)
