Answer to Question #137649 in Field Theory for Afraid

Question

Write K G equation

Answer 1

Solution

The Klein–Gordon equation (K G equation) is related to the Schrödinger equation and also a relativistic wave equation.

for $\hbar=c=1$ K G equation is given by

$\nabla^2\psi-\frac{ d^2\psi}{dt^2}=m^2\psi$
