De Broglie equation

[Alexis Robles 2k]

I was just wondering when do we use De Broglie equation? thanks

You use it to find the wavelength of an object(ie electron)

[Lauren Stack 1C]

De Broglie's equation is used to find the wavelength.
The equation itself is:
Wavelength = Planck's constant / (mass X velocity)
The units of planck's constant (m^2kg/s) cancel down to meters, as it is divided by mass (kg) and velocity (m/s) respectively.

Do you guys think that would be asked explicitly in the problem so we would know when to use it ?

Yes, it will ask for the "De Broglie wavelength" specifically. All the examples done in lecture have been that way.
