Evidence: The evidence to support the Muon experiment is that theoretically, Muon particles should be undetected at the surface of the earth because it has such a short life time.'2.2 x 10^-6 seconds' as measured in actual time. In actuality Muon particles are detected on the Earth's surface, and therefore provides evidence to support special relativity.
Conclusion: For the Muon's frame of reference the muon is experiencing proper time, but the length of the atmosphere is contracted to compensate for its speed.
For the observer on earths frame of reference the muon is is travelling at the proper length, but has an dilated life time.
H.5.2 - Solve problems involving the moon decay experiment
H.5.3 - Outline the Michelson and Morley experiment
The experiment was carried through like the flash animation above. A beam of light would hit a half-mirror which would reflect half the light and let through half the light. By doing so the "aether" would supposedly assist the speed of the light or slow down the speed of light.
The aim of the experiment is to find the speed of the earth travelling through space. They were trying to measure the speed of the Earth through the Aether.
H.5.4 - Discuss the result of the M&M experiment and its implication
In the end, the M&M experiment failed, no matter which orientation or location they performed the experiment in the speed of light always remain consistent. Therefore the scientist disproved the existence of "Aether" as well as provide the evidence to support the first postulate of relativity. "The constancy of the speed of light"
H.5.5 - Outline an experiment that indicates that the speed of light in vacuum is independent of its source
The Pion Decay Experiment:
The experiment analysed the decay of a particle called the Neutral Pion into two gamma-ray photons. The speed of the Neutral Pion was known to be travelling at 99.9% the speed of light, therefore the speed of the two gamma ray photons that are ejected from the neutral Pion must be even faster than that.
In the end the speed of the Photons were measured to be consistent with the speed of light.
This proves that speed of light is constant !
