equation definition
How is the de broglie equation different from the actual wavelength equation? Is the debroglie only for moving objects?
Re: equation definition
I believe the difference is that de Broglie's equation includes matter. Matter according to the de Broglie has wave-like behavior and this equation, therefore, is meant to include how to calculate the wavelength of an object of mass. The wave equation we worked with initally (c=wavelength*v) did not include mass or momentum.

Re: equation definition
The De Broglie equations includes the mass and velocity of a given particle while the normal wavelength equation can also be associated with light. You can tell which equation to use in a given situation based upon the parameters listed in the question.

Re: equation definition
De Broglie equation describes the status of a single quantum, which includes the mass and velocity. Therefore, the object has to be in motion.
Re: equation definition
The De Broglie equation has to do with the matter. For instance, moving objects like a baseball. When solving for the wavelength of light, it is matterless.

Re: equation definition
You use De Broglie's equation for objects with mass. This includes everyday objects, electrons, and protons. You use E=hv when you are doing calculations for a photon since a photon has no resting mass.
