1. What wavelength of EM radiation (in nm) is needed to have photons with a minimum energy of 275 kJ/mol? What color light would correspond to this wavelength? HINT: start by finding energy of one photon, then frequency, then wavelength. 2. Radio waves can have wavelengths several meters long while dental x-rays have wavelengths of several picometers (1x10-12). Why is human exposure to radio waves safe over extended periods of time while dental x-rays can be dangerous over long periods...

05 Question (4 points) When a hydrogen atom absorbs a photon of electromagnetic radiation (EMR), the internal energy of the atom increases and one or more electrons may be energized into an excited state. The release of this extra energy as the excited state electron transitions back to a lower energy state results in the emission of a photon. These energy changes are responsible for the emission spectrum of hydrogen (shown below) and are described by the Bohr equation. AE...
