Quantum Mechanics Flashcards
1
Q
The amount of radiant energy emitted by an object at a certain temperature depends on ___
A
wavelength (E = hc/λ) and E = nhf
2
Q
Formula for the kinetic energy of an ejected electron (photoelectric effect)
A
KE = hf - W
3
Q
Why does an electron not spiral into the nucleus of an atom?
A
The electron is allowed to occupy only certain orbits of specific energies (the energies are quantized)
4
Q
Relation between circumference of an allowed orbit and wavelength of an electron
A
2(pi)r = nλ
