### De Broglie Equation

can you use the debroglie equation to find the energy of a photon?

### Re: De Broglie Equation  [ENDORSED]

The De Broglie equation is used to describe the wave properties of matter. That means that in order for it to work, your object must have some mass (which can be seen in the equation of the wavelength being equal to Planck's constant over momentum) . I don't believe photons have a mass, so this would not really be possible, but it would work for something like an electron or baseball.

The equations to find the energy of a photon would be E=hv

You could use the equation as an initial step to find the energy of a photon. You're finding the wavelength, and you can plug that into an energy equation.

The De Broglie equation is used to find the wavelength but you can find the energy of a photon by rearranging other equations.

No you would not use DeBroglie Equation to find the energy of a photon because the equation gives you the wavelength for particles of mass. To find the Energy of A photon you would the equation E=hv, you can derive v from the formula c = lambda * frequency (v)
