When to use the DeBroglie equation?

What does the DeBroglie equation look for and when do we use it (Like what does the problem asks for that requires the equation)?

The de Broglie equation is used for any particle with momentum and wave-like properties.

Anytime a problem gives you any of the following: frequency, wavelength, energy, mass, frequency, or the velocity of light and asks you to find a different term in the aforementioned list is when you would use the equation.

Also, an important note to remember is that as the mass increases them the wave-length of the mass gets smaller.

Any particle with wavelike properties that has momentum. They will give us the mass and velocity.

And to have wavelike properties it just has to be over 10^'15 correct?

I think you use De Broglie's for any time you are given any values toward the variables for conversions between them.
