Is Schrödinger's Equation Linear?

Click For Summary
SUMMARY

Schrödinger's equation is confirmed to be linear by demonstrating that any linear combination of its solutions remains a solution. Specifically, if ψ1 and ψ2 are solutions to Schrödinger's equation, then the expression (aψ1 + bψ2) is also a valid solution, where a and b are constants. This property is fundamental to the linearity of quantum mechanics and is essential for understanding superposition in quantum states.

Homework Statement



I am to show that Schrödinger's equation is linear.

Homework Equations





The Attempt at a Solution



I think it is sufficient to show that if psi1 and psi 2 are the solutions of Schrödinger equation, then any linear combination of them, say (a psi1+b psi 2) is also a soluton to that equation.

Am I missing something?

No, nothing. If you show that then the SE is linear.
