de Broglie vs Heisenberg

Postby Rebecca Epner 4A » Mon Oct 14, 2019 10:47 pm

Can someone explain how you will know when to use which equation? What should I look out for in the context of the problem to determine which equation is most appropriate?

De Broglie refers to wavelength, velocity and mass whereas Heisenberg refers to position and nuclear diameter.

To add on, the Heisenberg equation is specifically used in regards to uncertainty. The questions will usually ask you what the uncertainty in the velocity is or it will give you a range of values for velocity. This is your main indicator to use the Heisenberg equation over the deBroglie equation.
