A 1eV photon’s wavelength is 120nm. Using ratio technique, calculate the wavelength of 5eV photon.

1) The Sun cranks out about 4 x 1026 J/s, i.e. its radiant power pe = 4 x 10²6 W. For a square meter of area here on the Earth whose surface normal points directly to the Sun, how many watts are received? How many 550-nm photons would that correspond to? (The Earth-Sun distance is about 150x100 km.)
