Final tips
What is a good sign I should use DeBroglie's equation on a problem versus a different given equation?

Re: Final tips
De Broglie is wavelength = (h/mv).
Typically, if you have to compare de Broglie wavelengths between two particles of different mass/velocity (or momentum), you'd have to utilize the de Broglie equation.
Tip: see what the question is asking for, then plug in variables.
Hope this helps, and good luck on the final. You got this.

Re: Final tips
Usually debroglie is involved when dealing with mass and wavelegnth/frequency. (mass is part of the equation for p, momentum)

Re: Final tips
De Brogile's equation is wavelength=planck's constant/(mass times velocity) so I would look out for a problem in which you have to solve for one of those variables and are given the rest that you can plug in.

Re: Final tips
DeBroglie's is wavelength=h/mv, which you would use if you are given all but one of the variables in order to find that one.
