Solution

The energy of a photon can be calculated using the equation E = h * c / λ, where E is the energy, h is Planck's constant, c is the speed of light, and λ is the wavelength.

Given: h = 6.626 * 10^-34 J*s c = 3.00 * 10^8 m/s λ = 185 nm = 185 * 10^-9 m

Substitute these values into the equation:

E = (6.626 * 10^-34 J*s) * (3.00 * 10^8 m/s) / (185 * 10^-9 m)

E = 1.07 * 10^-18 J

So, the correct answer is C. 1.07 * 10^-18 J.
