For the wave of light you generated in the part b, calculate the amount of energy in 1.0 mol of photons with that same frequency (1.2×1010 hz ) and wavelength (0.026 m ). recall that the avogadro constant is 6.022×1023 mol−1.

4.79 J

Explanation:

The energy of a single photon is given by

where

is the Planck constant

f is the frequency of the photon

Here we have

so the energy of one photon is

Here we have 1 mol of photons, which contains

photons (Avogadro number). So, the total energy of this mole of photons is:
