Quantum Phenomena Flashcards
1
Q
What proves wave-particle duality?
A
- De Broglie wavelength
- Electron diffraction
- Photoelectric effect
2
Q
What is the de Broglie wavelength?
A
Every object with a momentum has a wavelength associated with it.
3
Q
What is electron diffraction?
A
When electrons diffract in the same way a wave would.
4
Q
What is the photoelectric effect?
A
When incident photons have enough energy to liberate an electron from the surface of a material.
5
Q
What is the equation for the de Broglie wavelength?
A
Wavelength = Planck constant / Momentum
