Re: Energy Equations
based on what you are given, both equations can be used to get to the unknown variable you are looking for
Re: Energy Equations
The equation you use is based on both the information you are given and what you are planning to solve for

Re: Energy Equations
You can use either equation to get the energy of a particle but I don't think you can use E=pc for photons as photons have no mass and therefore no momentum.

Re: Energy Equations
The equation depends on the variables given in the question, as well as what you're trying to solve for. You can combine/relate these two equations with each other, in order to solve for particular values.
Hope this helps!

Hi!
Depending on what information they give you, you could use either formula. Hope this is helpful (-:

Re: Energy Equations
it just depends if we are solving for frequency of wavelength based on the energy of a photon, E

Re: Energy Equations
Either will work, just be sure to pay close attention to what the questions asks for specifically. Pretty often, there are times when you use multiple equations to solve one problem!
Re: Energy Equations
It depends on the question or problem you're trying to solve for, such as if your solving for something with mass or something that is electromagnetic

Depends on the context. However, you should try to keep in mind that the de Broglie equation should not be used for light.

Re: Energy Equations
When solving for energy, both equations E=pc and E=hv=h(c/wavelength) are usable. It would just depend on what is given in the problem.
