e=hv

[705379941]

why is e=hv only applied to light ?

[Isabella Dal Porto 1H]

Lavelle discussed in class how light rays are streams of EM energy that are made up of photons. Thus, since a photon is a unit for light and E=hv measures the energy of a photon, the equation is applied to light.

[Lara Kristine Bacasen 1L]

The variable E denotes that a photon/energy particle of light is proportional to its frequency (v). Variable h relates the energy in one photon of electromagnetic radiation to the frequency of that radiation. It links the particle's frequency with its energy. So essentially, I believe that this equation can be used for anything on the electro magnetic spectrum but we use visible light as it is that range in which electrons are removed.

This equation was explained in class to be the energy per photon and since light consists of photons, E=hv is applied to light.

[Trent Yamamoto 2J]

e=hv is in regards to energy per photon, which directly relates to light.

[Letty Liu 2C]

Is the E=hV formula derived from the photoelectric experiment?

[cassidysong 1K]

Yes it was derived from the photoelectric experiment.

[SimranSangha4I]

e=hv references the energy per photon and it was derived from the photoelectric effect.
