Question:
(a) Suppose ϕL and AL satisfy the Lorenz gauge constraint. What equation must Λ satisfy to ensure that A' = AL − ∇ and ϕ' = ϕL + ʌ̇ are Lorenz gauge potentials also?
(b) What equation must satisfy to ensure that ϕ' satisfies the same inhomogeneous wave equation as ϕL? Show that the same equation for Λ' also ensures that A' satisfies the same inhomogeneous wave equation as AL.
