32. Electromagnetic Waves / The Doppler Effect of Light / Problem 2
An alien civilization sends signals toward Earth, and these signals are detected as radio waves with frequencies about 10% lower than those measured on Earth. Estimate the speed of the alien civilization's planet using the Doppler effect for light. How would your answer differ if you used the classical Doppler effect?
