The relationship between photons of light at various energies and wavelengths is Given by E=hv , c=v(wavelength) Therefore, when a photon of energy at wavelength of 275 nm is compared with photons of energy at wavelength of 390 nm and higher we have a decrease in the energy and its dissociation energy that would attack polymeric or chemical bonds of various structures. Therefore, the higher the wavelength the lower the frequency or higher wavelengths have less energy than lower wavelengths 275nm is far greater energy than 390nm or higher. Given we have established light is composed of photons and high energy gamma radiation are also photons but of higher energy does the math for photochemistry given above apply to higher sources of photon energy from gamma and other sources of radiation? If so why or why not.
