Time evolution of wave function in an infinite square well potential

Click For Summary
SUMMARY

The discussion centers on the time evolution of the wave function in an infinite square well potential, specifically analyzing the energy states represented by the expressions (-1)^(-1/8) and (-1)^(-9/8) using the formula exp(-iEt/ħ). The participant believes their answer corresponds to option (3), while the correct answer is indicated as option (4). This highlights the importance of accurately applying quantum mechanics principles in solving problems related to wave functions.

Homework Equations


For this question my ans. is coming option (3) since the time part of the wave comes out to be same for both the energy states which is (-1)^(-1/8) and (-1)^(-9/8) respectively (using exp(-iEt/ħ)).
But the correct option is given option (4).
Am I right??
