I'm a little confused on the difference? Are the spectrums not equivalent? I'd think there would be some relationship between intensity and absorption.

Are either emission and absorption spectrums the opposite of each other? What is the relationship between them?
shough
Would this object be a yellowish-green since it reflects green/yellow light and absorbs blue/red light?
spidey
How do the absorption and emission spectrums relate to one another?
gloose
Could we make an equivalent "reflection spectrum" computed as 100% - absorption for each wavelength? This feels like it would be much more intuitive (e.g. plants would actually peak at green, not blue and red), so why do we talk about absorption instead of reflection? (Edit: I see that you do use a reflection spectrum later in the lecture. Are there any cases where absorption is the more natural model to use?)
MrRockefeller
correct me if i am wrong, but i think objects' emission spectrum + absorption spectrum are just 1

I thought emission and absorption spectrums are different. According to my understanding, emission spectrums are for things that can produce light, and many objects cannot produce visible light in the normal condition. (correct me if I'm wrong)
