Challenge Problems
Push your limits with challenges.
Question 1
If an element absorbs light at 400 nm and you know the energy of the photon can be calculated using E = hc/Ξ», what is the energy absorbed? (Use h = 6.626 x 10^-34 JΒ·s and c = 3.00 x 10^8 m/s)
π‘ Hint: Remember to convert nm to meters.
Question 2
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.
π‘ Hint: Think about energy level transitions and how they relate to absorption.
