20. Consider the Schrödinger equation, which ones of the following descriptions of the wave function Ψ(x, t) are correct?
(A) The probability of finding the particle at position x and time t is proportional to |Ψ(x, t)|².
(B) The mass distribution of a particle at position x and time t is proportional to |Ψ(x, t)|².
(C) The mass distribution of a particle at position x and time t is proportional to |Ψ(x, t)|.
(D) If Ψ₁ and Ψ₂ are two possible wave functions to describe the state of a particle. Then Ψ₃ = (2/5) Ψ₁ + (3/5) Ψ₂ may be another state of the particle
(E) If Ψ₁ and Ψ₂ are two possible wave functions to describe the state of a particle. Then Ψ₃ = (3/5) Ψ₁ + (4/5) Ψ₂ may be another state of the particle
