Showing Superposition Principle with Time-Dependent Schrödinger Equation

Click For Summary
SUMMARY

The discussion centers on demonstrating the superposition principle using the time-dependent Schrödinger equation. It is established that if ψ1 and ψ2 are solutions to the equation, then the linear combination c1ψ1 + c2ψ2, where c1 and c2 are arbitrary constants, is also a solution. The key method to prove this involves substituting the combination into the Schrödinger equation and verifying that it satisfies the equation. This approach confirms the validity of the superposition principle in quantum mechanics.

Homework Statement


Show that, if psi1 and psi2 are both solutions of the time-dependent Schr¨odinger
equation, so is c(subscipt1) psi1 + c(subscript2) psi2 (where c1 and c2 are arbitrary constants).

The Attempt at a Solution


every source I've consulted so far just states it as a fact. i know its somthing to do with the superposition principle but how do i literally show what they ask? its only a 2 markk que
thanks in advance

Just plug that combination into the Schrödinger equation and show it satisfies the equation.
