1
Q
What is Red Shift?
A
the increase in wavelength of light emitted from a surface that is moving away from you
2
Q
What happens when a light source moves away from you?
A
the wavelength of the light that it emits increases and the frequency decreases
3
Q
What happens if a light source is moving away from you faster? What happens if it is moving towards you?
A
Moving Faster = the red shift is bigger
Towards you = light is blue shifted
4
