Exploring Quantum Physics - Week 4 Bonus Question 2

Question:

What is true about $ \hat{I} \psi_0(x) $? The operator is defined as $ \hat{I} \psi(x) = \psi(-x) $.

Solution:

$ \psi_0(x) $ is an even function, so these are correct choices:

$ \hat{I} \psi_0(x) = \psi_0(-x) $.
$ \hat{I} \psi_0(x) = \psi_0(x) $.
