Document Summary
Venus, because it is closer, and the lack of light (since all light travels at the same speed) from venus would reach us first. If a star is moving away from us at 200 km/s, its light will be . Prof. kipping will take over starting next thursday. The flux (f) or brightness (b) you observe drops off with distance from the object. Peak lambda emitted by an object is related to temperature. Lambda of max = 2. 9 x 10^6 (nm k) / t(k) nm = nanometer = Electrons can absorb light and gain energy or emit light and lose energy. The only allowed changes in energy are those corresponding to a transition between energy levels. Each type of atom has a unique spectral fingerprint. Our solar system is the only detailed reference point we have for planets throughout the universe. Possible types of planets we will find elsewhere in the universe.
