WebHappy World Quantum Day! Why April 14th? Planck’s constant is 4.14 x 10^-15 (or 0.00000000000000414) electron-Volts-per-second (eV/s) - this connects the energy of a photon & its colour. Find out how we're celebrating #WorldQuantumDay: … 14 … WebAs a result, a photon with an energy of 4 X 10-15 J has a wavelength of 500 nm. Problem: If the energy of a photon is 2.19 × 10 11 ev, determine the wavelength of that photon. Given parameters: Energy of photon E = 2.19 × 10 11 ev. ∴ E = 2.19 × 10 11 X 1.6 X 10-19 ∴ E = 3.05 × 10-8 J =350 X 10-10 J
