Question

How do you calculate the energy of a photon with a frequency of 501 nm?

Answer 1

It should be "a wavelength of 501nm." To calculate the energy of a photon, we use \(E=h\nu\) or \(E=\large\frac{hc}{\lambda}\).
\(h\) is the Planck's constant, \(6.626\times 10 ^{-34}\) J.s
\(c\) is the speed of light, usually \(3\times 10^8\) m/s
\(\nu\) is the frequency, in Hz.
\(\lambda\) is the wavelength, in m.
In this problem, you are given the wavelength so we should use the second formula
