What is the value for the constant for the speed of light?
Light travels through vacuum at a speed of approximately 186,000 miles per second. The distance of the sun from earth is approximately 93,000,000 miles. - Thus it takes (ans….) minutes for light to travel from the sun to earth. Proxima Centauri has a distance of approximately 2.5x 10^13 miles. - it takes sunlight (and….) years to reach Proxima Centauri. (Assume that a year has 365.25 days.)

Your answer is partially correct. A distant galaxy emits light that has a wavelength of 634.5 nm. On earth, the wavelength of this light is measured to be 639.0 nm. (a) Decide whether this galaxy is approaching or receding from the earth. (b) Find the speed of the galaxy relative to the earth. (Give your answer to 4 significant digits. Use 2.998 x 108 m/s as the speed of light.) (a) The galaxy is (b) Number receding 2126000 from the earth. Units m/s
