Question

Use uncertainty analysis to estimate what is the smallest wavelength separation that can be resolved. In other words, what uncertainty would be expected for measurements of wavelength with the spec- troscope? Assume that the diffraction grating has 600 lines/mm and you are looking at wavelengths around 600nm. Use the error estimates outlined in the error analysis section. Will you be able to reliably resolve all the spectral lines of helium, sodium, and cad- mium? If not, list what sources of uncertainty would need to be decreased.

Answer 1

R=-=mN Helium for 438.793nm and 443.755nm 600 4.962 -120.91 443.755nm to 447.148nm R= similarly it goes on for the resolution. 600 3.393 - 176.83
