Einstein's Special Theory of Relativity
What was Einstein's DOB and DOD? - Answer- 1879 - 1955
What was Galileo's Principle of Relativity? - Answer- All observers who move
uniformly relative to each other are equal,and no absolute state of motion can be
attributed to any observer
What was James Clerk Maxwell's DOB and DOD? - Answer- 1831 -1879
What did Maxwell do in the field of electromagnetism? - Answer- 1. Showed that
electric and magnetic fields travel as waves at the speed of light
2. Suggest they are waves in the ether
When did the Michelson-Morley experiment take place? - Answer- 1887
What was the main goal of the Michelson-Morley experiment? - Answer- To measure
the speed of the earth's motion through the ether
What were the specifics of the Michelson-Morley experiment? - Answer- 1. They
measured differences in the speed of light in different directions relative to the earth's
motion
2. The speed of light seemed to be constant
3. They failed to detect any motion of the earth through the ether
4. This was the first piece of evidence suggesting the ether doesn't exist
When did Einstein publish his theory of relativity? - Answer- 1905
What are the basics of Einstein's theory of relativity? - Answer- 1. He said the speed
of light was a constant, c = 3 x 10^8 m/s
2. If I am travelling at velocity v, away from a light source, I measure the speed of
light as c, not c-v as Newton suggested
What are the two axioms Einstein based his Theory of Relativity on? - Answer- 1.
Light always travels at the same speed through an empty space regardless of the
motion of the source/observer
2. No experiment can ever be performed that is able to detect absolute motion
(Galileo's principle)
What were Newton's and Einstein's rule for combining two velocities? - Answer-
Newton: V = v1 + v2
Einstein: V = (v1 + v2)/(1 + v1v2/c^2)
Who's velocity equation works best with small velocities? - Answer- Einstein's and
Newtons equations will give nearly the same answer
Who's velocity equation works best with large velocities, i.e. close to the speed of
light? - Answer- Einstein's
