In the context of the wave equation, 'classical' means that the equation applies to macroscopic and low-speed situations. It is rooted in the Newtonian viewpoint, distinguishing it from quantum mechanics (microscopic) and relativity (high-speed).
Conditions: The discussion is about the domain of applicability of physical equations.; 'Classical' is contrasted with 'microscopic' and 'high-speed'.
