Unformatted text preview: Star A gives off most of its light in the infrared. Star B gives off most of its light in the ultraviolet. Which of the following statements is true? 1) Star A is cooler than Star B. 2) Star B is cooler than Star A. 3) Star A and Star B have the same temperature. 4) There is not enough information to answer this question. What type of spectrum is produced by a hot, thin gas? Answer: emission spectra A blue photon of light and a red photon of light leave a distant star. Which photon of light has more energy? 1) The blue photon has more energy. 2) The red photon has more energy. 3) Both photons have the same amount of energy. What type of spectra can be described as having light emitted at all wavelengths with no sharp peaks or dips? 1) Continuous spectra. 2) Emission spectra. 3) Absorption spectra. If light is emitted from a source moving toward you the speed of the light will appear faster than it truely is....
