2 cards from this section. Quick, good the night before a test.
What is the photoelectric effect?
Think about what happens when light shines on a metal.
Define wave-particle duality.
Consider examples of both light and electrons.
What does the photoelectric effect demonstrate?
Focus on the role of photons.
Is it true that de Broglie’s hypothesis suggests that matter has wave-like characteristics?
Recall the formula for wavelength.
A zinc plate is illuminated by UV light and emits electrons. Discuss the relationship between the light's frequency and the energy of the emitted electrons.
Refer to Einstein's photoelectric equation.
Using de Broglie’s hypothesis, calculate the wavelength of an electron with a velocity of 1.5 x 10^6 m/s and mass of 9.11 x 10^-31 kg.
Don't forget to calculate momentum first.
