De broglie equation versus E=hv

[samanthaywu]

What is the difference in use between the DeBroglie wavelength equation and the E = hv equation in terms of applications?

[Allan Nguyen 2G]

I believe the De broglie equation is used when determining whether the object being evaluated has wavelike properties or not. For example, if you're given the energy of an object that is not light, you can use the E=hv equation to find the velocity and use that velocity to plug into the De broglie equation to find the wavelength. This topic was from a while ago so I'm kinda rusty on the topics.

E=hv is used to find the energy of a single photon of light when it interacts with a single electron. The DeBroglie equation is used to find the wavelength/wavelike properties of objects, but they could be used together in a problem as mentioned above.

An easy way I remember is that particles with mass cannot be traveling at the speed of light, so you can only use the debroglie equation when considering photons and particles without mass.

[Katie Le 3K]

In terms of application, de broglie can be used on any object as it has mass as a variable. Whereas e=hv is for energy of a photon.

The De Broglie Equation is used to find wavelengths with a mass while E=hv finds the energy of a photon at a given wavelength

[Jeremy Wei 2C]

I believe the debroglie's equation is for objects with mass, while E = hv can be only used for photons.

Use De brogiles for molecules that have a rest mass and use E=hv for electromagnetic radiation like light photons

[Olivia Monroy 1A]

De Broglie calculates the wavelength for molecules with a mass (e-, neutrons, protons) while E= hv is the energy per photon. When you find the wavelength of the particle you will see the speed has to be less than the speed of light.

[Erika Sosa-Cruz 1J]

E=hv can only be used for photons.

[Rainy Liu Ruoshui_2K]

De Broglie equation is used to calculate the energy of electrons as waves, but E=hv applies for the energy of light in photoelectric effects.
