В I |Revisión 田 !!!How the photon energy unit J is changed into pJ (pico-joule) by hand Please explain how to multiply or divide powers of ten (i.e. factors that look like 10x)A hydrogen atom is heated up causing an electron to be excited to a level which we will call E2. When the electron falls back to the E1 energy level, it emits a photon of light. The photon has an energy of 267.039 fJ. What is the energy change (∆E) of the electron when it falls from E2 to E1? Enter your answer just as a number with units of fJ. ∆ is final minus initial. Recall from thermo that the total energy change will be zero. (Light always has a positive energy).
