What's an Ion's sound speed (Cs) in a plasma?

In summary, an ion's sound speed (Cs) is the speed at which sound waves propagate through a plasma, and it can be calculated using the equation Cs = √(γkT/m). This parameter is affected by the temperature, density, and composition of the plasma, as well as the mass and charge of the ions. It is directly proportional to the square root of the ion temperature, making it an important factor in understanding the behavior of plasmas in terms of stability, dynamics, and energy transmission.

Summary: Is it the same as Bohm velocity ?

Is it the same as Bohm velocity ?

I easily found the equations for the Bohm velocity and ion speed of sound in a plasma. Perhaps you should try putting some numbers into both equations and seeing what you find.
