photons of light headed towards earth from the surface of the sun measures between 290 nm and <400nm what is the lowest possible energy for a photon whose wavelength measures between 290nm and 400nm
Homework Answers
Energy of photon is inversely proportional to wavelength.So at highest wavelength the photon has less energy.So the lowest possible energy is at 400nm.

2. Ultraviolet light emitted by the sun has wavelengths between 200 nm and 400 nm. Visible light is between 400 nm and 700 nm. Will a photon of ultraviolet light from the sun break the chemical bond in an oxygen molecule, which has an energy of 494 k.J/mol? Will a photon of visible light break this bond?

The energy of a mole of photons of light in the electromagnetic spectrum decreases logarithmically as a function of increasing wavelength. In the visible range, light has between 40 and 80 kcal/mole of photon energy. Below about 400 nm wavelength, the energy increases significantly. Use what you know about the energy of chemical bonds to make an argument in favor of using sun screen with UV-block on a sunny day.

Nuclear fusion reactions at the center of the sun produce gamma-ray photons with energies of order 1 MeV (106 eV). By contrast, what we see emanating from the sun's surface are visible-light photons with wavelengths of order 500 nm. A simple model that explains this difference in wavelength is that a photon undergoes Compton scattering many times - in fact, about 1026 times, as suggested by models of the solar interior - as it travels from the center of the...
