3 cards from this section. Quick, good the night before a test.
Define what a photon is.
Think about how light is composed.
What is the relationship between the frequency of light and the energy of its photons?
Recall the terms high and low frequency.
What is a photon?
Think about how light is composed.
True or False: Higher frequency light possesses lower energy photons.
Remember the energy-frequency relationship.
Consider a material with a threshold frequency for electron ejection at 5 x 10^14 Hz. Calculate the minimum energy of a photon needed to eject an electron.
Use Planck's constant for your calculations.
If red light has a frequency of approximately 4 x 10^14 Hz and blue light has a frequency of approximately 6 x 10^14 Hz, how does the energy of a blue photon compare to that of a red photon?
Think about how the energy equation connects to frequency.
