1. If a star or galaxy is moving away from us, its wavelength will shift which way? 2. If a star or galaxy is moving towards us, its wavelength will shift which way? 3. In 30 words or less, give an example of the Doppler Effect. Towards the red side. RED SHIFT Towards the blue side. BLUE SHIFT When a fast object goes by, you can hear it’s pitch get higher as it approaches and get lower when it passes.
