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 (6.6 × 10^-34 m^2kg/s),
c is the speed of light (approximately 3 × 10^8 m/s), and
λ is the wavelength.

Given that the wavelength is 584 nm, we first need to convert this to meters:

1 nm = 10^-9 m, so 584 nm = 584 × 10^-9 m = 5.84 × 10^-7 m.

Substituting these values into the formula gives:

E = (6.6 × 10^-34 m^2kg/s × 3 × 10^8 m/s) / 5.84 × 10^-7 m
= 3.4 × 10^-19 J

So, the energy of photons at this wavelength is 3.4 × 10^-19 J. Therefore, the correct answer is A. 3.4 × 10^-19 J.
