Color Question
« on: March 01, 2016, 08:38:40 PM »
In a Chem Lab we found how much of this light was absorbed by a green/blue solution. It absorbed the most of the light when this light's wavelength was at 700 nm, which was a red/orange light, the complementary color of the solution. What does this tell me about what wavelengths were actually absorbed?

What exactly do you want to know? You've already said that it absorbs light at 700 nm... Are you looking to figure out the why?

A site like this might start to help: https://www.wou.edu/las/physci/ch462/tmcolors.htm

Or you could, you know, Google it.

I want to know why the complimentary colored light gets absorbed the most. So why this green liquid absorbed the red light the most out of the rest of the colors

A white light source has (idealized) light of all wavelengths - colors, if you will. If you pass it through a solution that absorbs all the red light, what is left when it reaches your eyes?

I'm guessing it's every color besides the red, so it would be the green?

Pretty much. That site I linked to previously explains this. This image even happens to show for the colors you're talking about:
