3 cards from this section. Quick, good the night before a test.
What is a photon?
Think about the nature of light.
What is the formula for calculating the energy of a photon?
Identify the relationship between frequency and energy.
What is the energy of a photon given by the equation E = hn?
Recall the components of the equation.
True or False: Photons have mass.
Consider the nature of photons.
If a photon has a frequency of 5 × 10^14 Hz, calculate its energy.
Substitute the frequency into the energy equation.
A photon interacts with an electron and transfers 1.2 × 10^-16 J of energy. What frequency must this photon have?
Rearrange the equation to solve for frequency.
