3 cards from this section. Quick, good the night before a test.
What is the formula for calculating the energy of a photon?
Remember the relationship between energy and frequency.
What is produced when an electron drops to a lower energy level?
Consider what happens during energy transition.
What happens when an electron transitions from a higher energy level to a lower energy level?
Consider what energy change occurs during the transition.
True or False: The absorption spectrum is produced when electrons emit photons.
Think about the process that creates dark lines in the spectrum.
If an atom emits a photon of wavelength 500 nm, what is the energy of that photon? Calculate it.
Remember to convert nanometers to meters before performing your calculation.
Explain how the color of light emitted by a heated gas can indicate its composition. Use the concept of emission spectra in your answer.
Consider how each element has its own set of energy levels and transitions.
