How do changes in light wavelengths support the big bang theory?
A.Lights from other galaxies shifts toward the red end of the spectrum, which shows that the galaxies are moving away from the earth.

B.Lights from other galaxies shifts toward the blue end of the spectrum, which shows that the galaxies are moving toward the earth.

C.Lights from other galaxies shifts toward the red end of the spectrum, which shows that the galaxies are moving towards earth.

Lights from other galaxies shifts toward the red end of the spectrum, which shows that the galaxies are moving away from the earth.  (A)

A. Lights from other galaxies shifts toward the red end of the spectrum, which shows that the galaxies are moving away from the earth.

What is red shift in Doppler effect?

Redshift in doppler effect  is an example of the Doppler Effect. As an object moves away from us, the sound or light waves emitted by the object are stretched out, which makes them have a lower pitch and moves them towards the red end of the electromagnetic spectrum, where light has a longer wavelength.

The doppler red - shift of light observed from distant starts and galaxies gives evidence that the universe is expanding so , since it is a red light shift that means Lights from other galaxies shifts toward the red end of the spectrum and as the universe is expanding which shows that the galaxies are moving away from the earth.

hence correct option is A. Lights from other galaxies shifts toward the red end of the spectrum, which shows that the galaxies are moving away from the earth.
