What is the 'Doppler Effect'?
If a wave source is moving more relative to an observer there will be a change in the observed wavelength and frequency
1 of 8
In the 'Doppler Effect', what could the wave source be?
Light, sound and mircowaves
2 of 8
In the 'Doppler Effect', what happens to the wavelength and frequency of the wave source as it moves away from the observer?
The wavelength increases and the frequency decreases

What is 'Red Shift'?
The further away the galaxies are, the faster they're moving and the bigger the observed increase in wavelength- they then have a red tint to the observer, however, although this may be true, the observer may not be able to see this without

How does the effect of 'Red Shift' provide evidence for the Big Bang Theory?
It proves that the universe is forever expanding and that the universe started from a very small initial point
