Since lightmust travelo millions of light years, the light we see is millions of years old. How do we know that a star in a distant galaxy is still there? $200 red Objects we are moving away from appear $400 Doppler effect When you hear a siren change pitch as it approaches you this is an example of $600 No shift at all (not blue or red) so it will appear yellow The light from an object moving from right to left will exhibit $800 blue An object moving towards us would appear $1000 You can give its radial velocity, either towards or away from us. What information can be inferred about a star from its Doppler shift? $200 radio What type of wave has the lowest energy $400 halved If a waves frequency doubles it wavelength is $600 They both transfer energy. Sound needs a medium, light travels in space How are sound waves and electromagnetic radiation similar? How are they different? $800 Frequency times the wavelength A wave’s velocity is the product of the $1000 Sound travels through a material medium, and can not travel through a vacuum Why can you hear a tree fall in the forest but you can’t hear me slam the space capsule door in space? $200 Photon Individual packet of electromagnetic radiation $400 Spectroscopy An analysis of the way atoms absorb and emit light is $600 Kelvin Temperature scale that places zero at the point where all atomic motion ceases. $800 fourth According to Stefan’s Law: The total energy radiated by a black body is dependent on the _______________power of its temperature $1000 Wave Does diffraction show wave nature or Particle nature of light? $200 6 The distance between two crest is 6 cm and the distance from the median to the top of the crest is 4 cm. what is the wavelength? $400 ¼ or .25 Hz A wave has a period of 4 seconds, what is it’s frequency $600 It’s temperature The wavelength of an object’s blackbody radiation is dependent on? $800 Stefan’s If the sun’s temperature were doubled, it would give off 16X’s more energy is an example of what law? $1000 A few bright emission lines What kind of spectrum would a neon light give us?
