Question

question 38 what does the red shift of light from distant galaxies indicate? galaxies are moving towards us. galaxies are stationary. galaxies are shrinking. galaxies are moving away from us.

The red - shift of light from distant galaxies is a result of the Doppler effect for light. When a source of light (galaxy) moves away from an observer, the wavelength of the light is stretched, causing a shift towards the red - end of the spectrum.
