<span>Old age and hundreds of thousands to millions of member stars.</span>
In longitudinal and transverse waves<span>, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction (respectively) relative to the direction of energy transport. In a </span>surface wave, it is only the particles at the surface<span> of the medium that undergo the circular motion.</span>
The wave equation is
Wave speed = (frequency) x (wavelength)
When any two of the three variables are known, the wave equation can be used to determine <em>the third variable</em>.
