Since the x-axis for these graphs are wavelength and v is frequency, how would that change the graph, if at all?


I don't recall ever looking dim in the mirror. Does this mean that a mirror reflects most visible light at near 100%?


i have a question about materials' absorption spectrum. when striked by same frequency but different intensities, is the reflected percentage always proportional? like maybe when light is too strong it will have phase change?


Aside from the surface's reflection values, could it also be emitting some different spectrum of light on its own? If so, how do the surface's emission spectrum and reflection spectrum interact in the final color we see?
