Question #134414
Calculate the energy of a single photon of light with a frequency of 3.00×1016 s-1.
Expert's answer
The energy of a single photon can be calculated using Planck equation:
E = hf
where E - photon energy, h - Planck constant (h = 6.626 × 10-34 J s ), f - photon frequancy
From here:
E = 6.626 × 10-34 J s × 3.00 × 1016 s-1 = 19.878 × 10-18 J = 1.99 × 10-17 J
Answer: 1.99 × 10-17 J
