allena is a computer programmer working on a research project that uses images of galaxies to measure how fast the galaxies are moving and in which direction they are moving. her program analyzes the movement to show that the galaxies are moving away from each other. which property of light energy is analyzed by allena’s program?

Answer

Brief Explanations:

When galaxies move away from each other, the light they emit undergoes a redshift. This is an application of the Doppler - effect for light. The change in the wavelength of light (redshift) is analyzed to determine the motion of galaxies.

Answer:

Red - shift of light
