Determine the photon mass of 600 nm yellow light.

univerkov | September 11, 2021 | education

Data: λ – wavelength of propagating yellow light (λ = 6 * 10 ^ -7 m (600 nm)).

Const: h – Planck’s constant (h = 6.62607 * 10 ^ -34 J * s); C – speed of yellow light (C = 3 * 10 ^ 8 m / s).

To find out the mass of the indicated photon of yellow light, consider the formula: mph = h / (λ * C).

Let’s perform the calculation: mph = h / (λ * C) = 6.62607 * 10 ^ -34 / (6 * 10 ^ -7 * 3 * 10 ^ 8) ≈ 3.68 * 10 ^ -36 kg.

Answer: A photon of yellow light should have a mass of 3.68 * 10 ^ -36 kg.
