Web(g) absorbs a photon with a frequency of 1.00 × 1015 s−1. (i) How much energy, in joules, does the O 3 (g) molecule absorb per photon? E = hν = 6.63 × 10−34 J s × 1.00 × 1015 s−1 = 6.63 10× −19 J per photon One point is earned for the correct answer. (ii) The minimum energy needed to break an oxygen-oxygen bond in ozone is 387 kJ ... WebFeb 2, 2024 · To calculate photon energy from wavelength: Make sure your wavelength is in meters. Divide the speed of light, approximately 300,000,000 m/s, by the wavelength to get the wave's frequency. Multiply the frequency by Planck's constant, 6.626×10 −34 J/Hz. The resulting number is the energy of a photon! irish weather in march
