Red shift/Blue shift/ Doppler Effect

What color is the longest wavelength?

• Green

• Yellow

• Red

• Blue

Answer explanation

Red has the longest wavelength in the visible spectrum, ranging from about 620 to 750 nanometers. In contrast, green, yellow, and blue have shorter wavelengths, making red the correct answer.

Use the image to identify the motion of the object relative to Earth.  Compare the absorption spectra of the star (top row) to what the star would look like if it were not moving at all relative to Earth (bottom row).

• 
  It is not moving

• It is moving away from Earth (Redshift)

• 
  It is moving towards Earth (Blueshift)

• It is moving towards Earth (Redshift)
