What is a red/blue shift?

• The shift of spectral lines to the right or left of the visible spectrum, indicating it's motion

• The shift of spectral lines to the right or left of the visible spectrum, indicating it's motion and speed

• The shift of spectral lines to the right or left of the infared spectrum, indicating it's motion

• The shift of spectral lines to the right or left of the electromagnetic spectrum, indicating it's motion and speed

What is a red shift?

• The shift of spectral lines to the left of the visible spectrum, indicating it's motion and speed. It's moving towards the observer.

• The shift of spectral lines to the right of the visible spectrum, indicating it's motion and speed. It's moving away from the observer.

• The shift of spectral lines to the left of the visible spectrum, indicating it's motion. It's moving towards the observer.

• The shift of spectral lines to the left of the visible spectrum, indicating it's speed. It's moving away from the observer.

What is a blue shift?
