Unformatted text preview: t • Is there a luminiferos ether?
Let’s find out! • Interferometers
Light: the ultimate yardstick. Last class we found a problem!!
Mr. Maxwell told us, the speed of light ‘c’ is: c 1 0 0 3.00 108 m / s Mr. Galileo told us that c’ = c – v
If the laws of physics are the same in all
inertial frames then ε0 and µ0 (and c) have
to be the same in all inertial frames. So let’s make up the “luminiferous ether” to fix Galileo’s velocity transformation law (u’ = u - v)!
(We will have to check if there is a luminiferous ether!..) Peculiar light-waves
• A sound wave propagates through air, with a
velocity relative to the air...
