WebThat means that for every joule of electrical energy (joule = watt * second) a certain number of photon micromoles are produced. One micromole = 602,000,000,000,000,000. That’s a dizzyingly large amount of photons! … Web27 mrt. 2024 · What is the energy of a photon with wavelength 450 nm? The energy of this photon is 2.75 eV. To find this result: Find the frequency: divide the speed of light by the wavelength: f = 3E9 m/s/4.50E-7 m = 666.2E12 Hz = 666.2 THz Multiply the frequency by Planck's constant: E = h × f = 666E12 Hz × 6.626 m²·kg/s = 4.41E-19 J

WebYes, the water temperature does affect the UV output of low-pressure UV lamps (not very much for low-pressure high output or medium pressure UV lamps). The optimum operating temperature for a UV lamp operating in the open is about 40 C (104 F). At 20 C (68 F), the output drops to about 50% and to about 10% at 0 C (32 F).
