Chemistry wavelength equations
WebE = hc / λ--- use this equation when asked to calculate E after being given the wavelength. Rearrange to group the variables and the constants: Eλ = hc (d) The mathematical relationship is an inverse one. Note the equation's similarity to λν = c, with two values that can vary on the left side and a constant (h times c) on the right. WebThe comparison of the efficiency of the commercially available photocatalysts, TiO2 and ZnO, irradiated with 365 nm and 398 nm light, is presented for the removal of two antibiotics, sulfamethazine (SMT) and sulfamethoxypyridazine (SMP). The •OH formation rate was compared using coumarin, and higher efficiency was proved for TiO2 than ZnO, while for …

WebWavelength (λ): In a wave the distance between any given point and the same point in the next wave cycle. This can be crest-to-crest, trough-to-trough, null-to-null, etc. Wavelength is related to energy and frequency by E = hν = hc/λ, where E = energy, h = Planck's constant, ν = frequency, c = the speed of light, and λ = wavelength. Webwhere ν is the frequency of the wave, λ is the wavelength, ω = 2 πν is the angular frequency of the wave, and vp is the phase velocity of the wave. The dependence of the …
