Knowing Which Equation to Use
When approaching quantum problems, what is your method to determine which equation we should be using?

Re: Knowing Which Equation to Use
I use Dr. Lavelle's problem solving guidelines:
1. What is the question?
2. What concepts do I know?
3. What model or equations do I know?
4. What is known? What is unknown?
5. Can I express unknown with respect to the known?

I usually start by figuring out what variables I know and then finding an equation that has the unknown variable in it, filling in all the known variables that apply to that equation.

At the moment, I'm distinguishing them based off of electromagnetic radiation and the quantum mechanics of electrons. For example, De Brogile's equation can only be applied to electrons, NOT light.

Re: Knowing Which Equation to Use
I usually begin by circling the quantities and units given in the problem, and what type of unit I need to find. Then, I just find which equation allows me work between what is given and the unknown.
