Motion lesson 12

OUTCOME

By the end of this lesson you will be able to describe Maxwell's observation and explain why it is relevant to our understanding of relativity

Michelson and Morley tried to measure the speed of the Aether wind but where unable to do so.

Einstein made two postulates that are the basis of special relativity

Minkowski or space -time diagrams can help us process and explain scenarios in which the speed of light is NOT relative but constant

LEARNING TASKS

Explain

1. What do they mean by saying the Aether represented the universal frame of reference.

2. What did Michelson and Morley expect to find from their experiment?

3. What did Einstein propose as a result of the Michelson Morley experiment?
