When a certain element is excited with electricity, we see three main lines in its emission spectrum: two red lines and one orange line. what would the absorption spectrum of this element look like?

The absorption spectrum would have all the wavelengths of the light source but would have black lines where the two red and one orange lines were in the emission spectrum

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.

Biased means unfair but that's all ik
