3 cards from this section. Quick, good the night before a test.
What do absorption spectra indicate?
Think about dark lines on a spectrum.
What is a photon?
It's a particle of light energy.
What happens to an electron when it absorbs a photon?
Consider transitions and energy changes.
Absorption lines in a spectrum indicate that light has been absorbed by what?
Think about the meaning of dark lines in a spectrum.
If an element absorbs light at 400 nm and you know the energy of the photon can be calculated using E = hc/λ, what is the energy absorbed? (Use h = 6.626 x 10^-34 J·s and c = 3.00 x 10^8 m/s)
Remember to convert nm to meters.
Using the absorption spectrum of an element, you notice dark lines at 450 nm, 500 nm, and 600 nm. Explain how this relates to the electronic structure of the atom.
Think about energy level transitions and how they relate to absorption.
