Quantum Mechanics Quiz Explanations
- H Ψ = E Ψ, is the Schrödinger’s wave
equation. The left hand side is the
Hamiltonian, i.e., the total energy (kinetic
energy + potential energy).
And the right hand side is E, the total
energy. It shows the conservation of energy
- Mass of proton is 1836 times that of
- Ψ doesn’t have any physical significance
as it’s a complex number, so we take its
complex conjugate and multiply with it to get
probability density. Max Born proposed this,
also called Born Interpretation of quantum
- <ΨI is a bra vector. And IΨ> is a ket
vector. They make up together to give
<ΨIΨ> , which complets to form a bra-ket.
- We use summation for adding up discrete
quantities. However, we use integration
while adding up continuous quantities.
