What stops them?What decides which element an atom belongs to?What name is given to a single self-contained packet of electromagnetic energy?A star is moved to ten times its present distance from us. How much fainter does it look?Wien's law uses a constant of 3 million nanometer kelvins. A star radiates most strongly at 500 nanometers. WhTwo stars are the same size and the same distance away, but star B is three times as hot as star A. How much mA hydrogen line normally at 500 nanometers is measured at 500.1 nanometers in a star's spectrum. What does thaAn oxygen atom can be ionized up to eight times while a hydrogen atom can be ionized only once. What sets thatDark lines cross the spectrum of the Sun. Where do the atoms that remove those colors sit?Excited atoms give back the very light they absorbed, yet dark absorption lines still survive. Why?
