Question

A photon has a frequency of 7.10x10^8 Hz. Calculate the energy of 1 mole of photons with this frequency

Answer 1

The energy of one photo is given by Planck's law:

\[E = h\nu\]where \[h \approx 6.626*10^{-34} \text{ kg m}/\text{s}^2 \text{ (aka Planck's constant)}\]and \(\nu\) is the frequency. Don't forget to multiply by the appropriate constant to find the energy of a mole of those photons.
