Question

directions: choose the best answer for each question. 1. evidence for the big bang theory is supported by the observation that light from distant galaxies shows a shift toward a. shorter wavelengths (blue shift) b. longer wavelengths (redshift) c. higher frequencies (gamma rays) d. smaller amplitudes (dimmer light)

Explanation:

The Big - Bang theory is supported by the observation of cosmic expansion. As galaxies move away from us, the light they emit experiences a redshift, which means the wavelengths of the light become longer.

Answer:

B. longer wavelengths (redshift)
