If light from a distant star passes close to a massive body, the light beam willGroup of answer choicesaccelerate due to gravity.bend towards the star due to gravity.continue moving in a straight line.change color to a shorter wavelength.slow down.

Why does redshift occur?5 pointsThe wavelength of light increasesThe wavelength of light decreasesThe celestial objects are moving fasterThe celestial objects are moving slower

“Transit” is when…Group of answer choicesa planet changes its average distance from its stara planet blocks some of the light of its starthe light of a star redshifts more than 2 nmbinary stars move into a new cluster of stars

While examining the spectrum of a galaxy you find all the hydrogen lines are shifted to longer wavelengths. This galaxy isGroup of answer choicesmoving away from us.moving towards us.expanding explosively.not forming new stars.blue shifted.

If the spectrum of a star is red shifted, it is moving away from you. True False

Einstein's theory of relativity gained a great deal of credibility by successfully predictingGroup of answer choicesThat light travels in straight linesThat light is a gasThat light comes from starsThat light "bends" around massive objects
