How does spectroscopy provide evidence for the big bang theory?
A: The red shift shows that galaxies are moving away from each other.

B. The intensities of peaks show that galaxies are moving toward each other.

C. The intensities of peaks show that galaxies are moving away from each other.

D. The red shift shows that galaxies are moving toward each other.

The motion of stellar objects can be determined by looking at their spectrum. Because of the Doppler effect, objects moving towards us are blueshifted, and objects moving away are redshifted. The wavelength of redshifted light is longer, appearing redder than the source. Conversely, the wavelength of blueshifted light is shorter, appearing bluer than the source light.

Spectroscopy provides evidence for the big bang theory A: The red shift shows that galaxies are moving away from each other.

The Big Bang Theory is a theory that attempts to explain how the Universe came to be. Scientists believed that other galaxies in the planet were divergent from Earth at great speeds which was because of a great bang or explosion.

Therefore, the scientists use spectroscopy to show that the Big Bang actually happened because of the movement of red light using Doppler Effect.

The correct answer is option A.
