FactChecker replied to the thread High School Am I understanding the concept of proper frame of reference?.Ok. That could allow the case that a non-accelerated observer is also at rest and can still be called a proper reference frame. So it is...

FactChecker reacted to Ibix's post in the thread High School Why is the constant speed of light so unique? with Like.
As A.T. says, the speed of sound is constant with respect to the medium. In air it's about ##330\mathrm{ms^{-1}}##, but if you are...
