What is the angular separation of two spectral lines of wavelengths 417 nm and 388 nm formed in order m = 2 with a 456 line/mm grating?
What is the angular separation of two spectral lines of wavelengths 417 nm and 388 nm formed in order m = 2 with a 456 line/mm grating? If the two spectral lines are 2 cm apart, how far is the screen from the grating? I have the answer for the first have but not the second
