Final Unit 2 Flashcards
The system of quantum mechanics is completed specified by _____
the wavefunction
What does it mean to normalize a wave function
multiplying it by a constant to ensure that the sum of the probabilities for finding that particle equals 1
What does psi^2 tell us?
about probability
What are the necessary characteristics of a wavefunction?
must all have single values (ever x has 1 value of y)
continuous
finite
How do you tell on a graph how many nodes a wave function has?
The number of peaks is the number of nodes
When do classical and quantum mechanics overlap in wavefunctions?
if we reach a high enough energy classical=quantum
When does a node occur (equation)?
psi(x)=0 When the wavefunction goes to 0
How does wavelength and energy affect nodes?
As wavelength gets shorter, energy increases and it causes more nodes
What is the equation for the probability of position and how do you get the answer?
psi*(x)psi(x)dx
integrate between x1 and x2 to give u prob.
What is the Schrodinger equation?
Hhatpsi(x)=Epsi(x)
