Einstein’s second postulate tells us that the speed of light
slows in a transparent medium
depends on one’s frame of reference
is a constant in all frames of reference
changes depending on the time of day
2
Einstein stated that the laws of physics are
different depending on the situation
the same in all uniformly moving frames of reference
the same in all frames of reference
common sense applied to microscopic and macroscopic things
3

shorter in the direction perpendicular to travel
