Waves propagate by displacing a medium.
Waves propagate in the medium at one and only one velocity.
The luminiferous ether.
Galilean Transformation:
Relativity of rectilinear motion.
Early measurements of the speed of light:
The role of Jupiter’s moons.
Fizeau’s experiment regarding
drag of the ether.
Stellar
aberration and
the ether
Measuring the speed of light (Phys 3650 method):
Waves propagate by displacing a medium.
Waves propagate in the medium at one and only one velocity.
To test the idea, we will need to understand the concept of the interference of light.
Let’s review Young’s classical double slit experiment:
Michelson-Morley experiment
