Multiple choice  The relationship between wavelength and frequency is: 1- wavelength is double frequency  2-wavelength is independent of frequency  3-wavelength increases as the frequency decreases  4- wavelength is one half of the frequency  5-wavelength increases as frequency increases

If an atom has an emission line at a given shade of color (e.g., hydrogen at 656 nm), then does that atom have an absorption line at that same shade of color? Use the slider button under the label km/s to change the speed of the glowing object: negative speeds for objects approaching us, and positive speeds for objects recessing from us.  Describe changes to each of the continuous spectrum, emission line spectrum, and absorption line spectrum as the speed changes.  This change is called the Doppler effect, and is essential for measuring the speeds of objects located at a distance. Suppose you were given a spectrum of a planet.  The spectrum has a collection of absorption lines.  Describe how you would use this simulation to identify what lines were present (or absent) in the spectrum, and therefore what atoms were present (or absent) on the planet.
