### Light waves

Can we use this equation for light waves?

You only use De Broglie when dealing with a particle with momentum, typically having mass and velocity. When solving for light waves, you would use E=Hv, and c=wavelength*v

### Re: Light waves

You can only use c=(wavelength)(frequency) and E=h(frequency) for light waves. De Broglie's equation is used only for things with mass, and light does not have mass. Therefore, De Broglie can not be used for light waves.
