I understand how polarization can be explained using EM waves. However, I am unable to understand how to explain how polarization filters work when we use the concept of photon spins. Can someone help me with that?

Hi DaleSpan, Thanks for the answer. However, I am still a little confused. What is the simplest experiment that can prove this invariance? I believe we can't use the Michelson-Morley experiment as one because all the measurement devices and the light source were in the same frame of reference.

Hi, As far as I know the speed of sound is also constant irrespective of the speed of the source. I guess, this is an obvious result of the property of waves. So, why is the constancy of speed of a light wave more important? Please point out if there are any mistakes in my assumptions.
