The energy of a photon can be calculated using the formula:

E = hc/λ

where:
E is the energy of the photon,
h is Planck's constant (4.135667696 x 10^-15 eV.s),
c is the speed of light (299792458 m/s), and
λ is the wavelength of the light.

First, we need to convert the wavelength from nanometers to meters. 1 nm = 10^-9 m, so:

λ = 325.0 nm = 325.0 x 10^-9 m = 3.25 x 10^-7 m

Now we can substitute the values into the formula:

E = (4.135667696 x 10^-15 eV.s x 299792458 m/s) / 3.25 x 10^-7 m
E = 3.82 eV

So, the energy of a photon in a monochromatic beam of light with a wavelength of 325.0 nm is approximately 3.82 eV.
