Problem data: ν (frequency corresponding to the considered photon) = 2 * 10 ^ 15 Hz.

Reference values: h (Planck’s constant) = 6.626 * 10 ^ -34 J * s; C (speed of light) ≈ 3 * 10 ^ 8 m / s.

To determine the mass of the photon in question, we will use the formula: m = h * ν / C2.

Let’s make a calculation: m = 6.626 * 10 ^ -34 * 2 * 10 ^ 15 / (3 * 10 ^ 8) ^ 2 = 1.47 * 10 ^ -35 kg.

Answer: The mass of a photon is 1.47 * 10 ^ -35 kg.
