I have no idea where to start here..
this is the only question in this unit that has an angle in it... also not sure what second order means.
the angle of deviation of light of 400 nm wavelength is 30 degrees in second order. How many lines per cm are there on this diffraction grating if N = 1/d
any tips on how to get started?
thanks
