Wave equation and laplacian

  1. Feb 8, 2016 #1
    1. The problem statement, all variables and given/known data
    derive the following wave equation
    2H = 1/c2 (∂2H/∂t2)
    2. Relevant equations

    3. The attempt at a solution
    I'm not sure how to derive it. I suppose I can break it into a whole bunch of partial derivatives because of the del squared operator and then just lump the three partial derivatives (Hx, Hy, Hz) back into H but I don't know if that's a derivation of the equation.

    Derive from what ? Your relevant equations are missing, the problem statement is almost missing (we have no idea what H stands for). Have some compassion with helpers of good will !
