Unformatted text preview: 4.46, 4,68 Extra Problem: Look again at Equation 4.79. Assume light passes through a gas that has no free electrons and for low frequency light has only 1 important resonance frequency. Only one term in Eq. 4.79 will then be important (not the free electron term). Using this model, consider the index of refract of an ideal gas, where each molecule has a single resonance state. Assume the only resonance frequency is 1 eV . For gas at standard temperature and pressure and for wave length of light of 600 nm, the index of refraction is found to be 1.000300. a) What will the index be for the same conditions if the wave length of light is 800 nm? b) What will the index be for 600 nm light if the gas pressure is doubled with temperature held constant?...
