Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment During reflection does the emitted photon have same properties?
@WhatRoughBeast: the problem with the original question is that propagating light is poorly described as photons. The reflected wave will be the same as the incident wave except of course that its momentum points in a different direction.

comment Gravitational time dilation, does time of the observer at a lower gravitational potential looked slowed down in the frame of the higher one
@DanielLC: when $\Delta\Phi$ is large you need to use the metric that describes the curvature of your spacetime. The spacetime around the Earth is approximately described by the Schwarzschild metric, and you'll find lots of answers on this site explaining how to do the calculation.

comment What is the purpose of the imaginary portion of the wave function?
@CuriousOne: I'm not sure that's true. A real cosine wave is a perfectly acceptable solution to the Schrodinger equation. It's just not the most general solution.
