The energy of a photon can be calculated using the equation E = hf = hc/λ, where E is the energy, h is Planck's constant (6.626 x 10^(-34) J·s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength in meters. To find the energy of a 552 nm photon, we first convert the wavelength from nanometers to meters: 552 nm = 552 x 10^(-9) m. Then, we substitute the values into the equation: E = (6.626 x 10^(-34) J·s x 3.00 x 10^8 m/s) / (552 x 10^(-9) m). Performing this calculation yields the energy of the photon as approximately 3.537 x 10^(-19) J.
