Uh, open a vector analysis textbook? Or if you are able, think about the geometry of the situation?

In 3D vector algebra of physics, linear mass denasity and surface mass density are vector; shortly, I call them mass vector.

Prove it. You know, if what you say is true, it shouldn't be hard for you to demonstrate it to be true when you derive the wave equation.

When you find a negative surface, you can call it a vector. Perhaps you simply don't know what English words mean, "denasity" is a new one on me. Is it a Chinese, Korean, Mongolian, Japanese word, what?
