Initial data: P (photon impulse value) = 1.6 * 10 ^ -26 kg * m / s.

Constants: C (speed of propagation of sunlight) = 3 * 10 ^ 8 m / s.

The energy of a photon can be determined by the formula: E = P * C.

Let’s perform the calculation: E = 1.6 * 10 ^ -26 * 3 * 10 ^ 8 = 4.8 * 10 ^ -18 J = 4.8 aJ.

Answer: The energy of a photon is 4.8 aJ.
