The question in the title. Speed of sound in a medium obviously must be less than the speed of light. Speed of sound is usually given by the equation sqrt(c/p). Wondering what causes this to always be less than the speed of light.
Gar. Just realized something as I'm typing this. Now that I think about it, in the relativistic limit the equation would be different. As the particles in the wavefront started moving at a speed close to the speed of light they would gain mass. As they approached the speed of light the density would approach infinity.
I think I'll try and derive out what the actual equation is.
Leaving this up here in case people have interesting comments.
