    Graduate Why is the general form of the wave equation a second order partial derivative?

    I see. The first oder wave equation can not perfectly describe a wave. Thank you for link.

    Graduate Why is the general form of the wave equation a second order partial derivative?

    When I deduct the the general form of wave equation, I noticed it has a second order partial derivative form. I am wondering why wave equation has a second order partial derivative form nor a first order partial derivative form?
