The figure at the right shows transitions between three states of a molecule (labeled E1, E2, and E3) that are observed through the emission and absorption of photons in a pair of experiments, A and B.1. Which transition is associated with the emission of the photon of the longest wavelength?a b c d e2. Which transition is associated with the absorption of the photon of the shortest wavelength?a b c d e 3. If a cold gas of these molecules was in the atmosphere of a star that was emitting a continuous spectrum, you would expect to see some dark lines across the continuous spectrum from that star. This is because the molecules in the atmosphere of the star absorb some of the light emitted by the star. Which frequencies would you expect to be significantly blocked by passing through the cold gas?a. (E2 - E1)/hb. (E3 E1)/hc. (E3 E2)/hd. None of them.a b c d

Answer the following A. A comet has just passed the Earth and its peak emission is observed at 15000 nm. Determine in which region of the electromagnetic spectrum (e.g. X-ray, infrared, visible, ultraviolet, ...) the peak emission wavelength resides. What is the temperature of the comet? B. Within the Solar System, a convenient unit of measurement is the Earth-Sun distance, called an astronomical unit (AU). For bigger distances, we use the light year (LY), the distance that light travels in one year. We can expand our lingo to include other measures of distance, for example, light days, light minutes, and light hours. Starting with the values you can look up in the Appendices for the speed of light and the astronomical unit, calculate how many “light minutes” there are in 1 AU. C. What is the observable universe? How big is it?
