Question
Astronomers view light coming from distant galaxies moving away from the Earth at speeds greater than $10 \%$ the speed of light. How fast does this light meet the telescopes of the astronomers?
Step 1
This is a fundamental principle of physics, known as Einstein's theory of relativity. The speed of light in a vacuum is approximately $3 \times 10^8$ meters per second. Show more…

Astronomers view light coming from distant galaxies moving away from Earth at speeds greater than 10% of the speed of light. How fast does this light meet the telescopes of the astronomers?
Some distant star-like objects, called quasars, are receding from us at half the speed of light. What is the speed of the light we receive from these quasars? (Explain)
Some distant galaxies are moving away from us with speeds of 0.5c. What is the speed of the light that reaches Earth from these galaxies? Explain.
