hi,
i have a question here tt i hope some kind souls out there can clarify with me.
if i shine a monochromatic light, let's say 500 nm, at a diffraction grating, will i onli get spectral lines, or will there be some orders which give me an angular spread? cos when u draw the graph of intensity against sin(theta) for a monochromatic diffraction grating, u get a detectable spread for each peak.
