Question 195 out of 5 pointsThe Doppler effect causes the spectrum of an approachinglight source to be shifted toward which end of the spectrum? Answers: a. blue b. red c. There is insufficient information to answer the question. d. Neither. The colors do not shift at all, because the speed of light is constant. Response Feedback: The speed of light is constant, but color does vary depending on speed of approach or recession. The correct answer is blue, because the wave crests of light from an approaching light source are bunched closer together, making the wavelength shorter. Remember, blue light has shorter wavelengths than red light.
