1. A certain shade of blue has a frequency of 7.01×1014 Hz. What is the energy of exactly one photon of this light? E = ??? J 2. A dental X‑ray typically affects 195 g of tissue and delivers about 3.95 μJ of energy using X‑rays that have wavelengths of 0.0305 nm. What is the energy in electron volts of a single photon of these X‑rays? I got energy of a photon as: 40.7 x 10 ^3 which is correct but...
