What will I benefit or what will I gain if I know the absorbance and emission of any substance?
Over [174]

Answer:

You would gain science knowledge, like if you wanted a science career this is more-than-likely something you would have to learn.

Emission and Absorbance of substances:

-Emission is the process where a substance gives off or emits radiation when it is heated or treated chemically. The level of emission of a substance depends on its spectroscopic composition and temperature.

-Absorption is the process where the electrons of a substance absorb or take up the energy wavelengths incident on them.
