Quantum Flashcards
1
Q
Photocell
A
Shows number of electrons emitted per second
2
Q
Stopping Potential
A
Used to find kinetic energy of electrons as they leave the metal plate
3
Q
Electrons can move across energy levels by:
A
Absorbing a photon with the exact amount of energy needed
Colliding with another electron and gaining some Ek
4
Q
When an electron is excited:
A
It will return to its ground state by losing energy in the form of an emitted photon that has energy equal to the change in energy level.
