Question

multiple choice question
which of these formulas correctly expresses the relationship between the energy of a photon (e_photon) and its wavelength (v)?
o e_photon = h/v
o e_photon = 1/hv
o e_photon = hv
o e_photon = v/h

Explanation:

Step1: Recall Planck's equation

Planck's equation for the energy of a photon is \(E = h
u\), where \(E\) is the energy of the photon, \(h\) is Planck's constant (\(h = 6.626\times10^{-34}\space J\cdot s\)), and \(
u\) is the frequency of the photon.

Answer:

\(E_{\text{photon}}=h
u\) (the third option)
