AST 101 Midterm: Practice Exam 3
Document Summary
1- as the wavelength of light increases the energy carried by its photons. Practice exam iii oct 2014: increases, decreases, stays the same. 2- as the temperature of a star increases the peak energy output moves to: higher frequency, lower frequency, peak output is independent of temperature. 3- as the frequency of light increases, its speed: increases, decreases, stays the same. 4- the following are the energy levels of an atom that can emit red, blue and green light. 5- the following are the energy levels of the atoms making up a hot gas. Photons of energy 3 ev, 5ev and 8ev are incident on the gas. ______________________ 0: the photon of energy 3 ev, the photon of energy 5 ev, the photon of energy 8 ev, they all have the same chance of being absorbed, none of them will be absorbed. 6- a bright, hot star is embedded in a gas cloud.
