SUMMARY
The energy eigenfunction for a free particle is represented by a plane wave, typically expressed as Ψ(x) = Ae^(ikx), where A is the amplitude and k is the wave number. For a particle in a box, the momentum eigenfunctions are derived from the standing wave solutions, which can be expressed as Ψ_n(x) = √(2/L) * sin(nπx/L), where L is the length of the box and n is a positive integer. These functions are crucial for understanding quantum mechanics and are foundational concepts in quantum theory.
