SUMMARY

This discussion focuses on the relationship between Maxwell's equations and the wave equation in electromagnetic theory. It establishes that the electric field vector e and the magnetic field vector b, governed by Maxwell's equations, satisfy the wave equation (∂²/∂t² - ∇²)φ = 0. The key equations referenced include ∂e/∂t = curl b and ∂b/∂t = -curl e, along with the divergence conditions div e = 0 and div b = 0. The discussion suggests taking the curl of both sides of the first two equations to derive the wave equation for both fields.

how would i solve this?

Let respectively b = (b1, b2, b3) and e = (e1, e2, e3) denote the magnetic
and electric field in some medium. They are governed by Maxwell’s equations which look as follows:
(0.1) dte = curl b
(0.2) dtb = −curl e
(0.3) div e = 0
(0.4) div b = 0.
Show that each bi and each ei satisfies the wave equation
(dt^2-delta)phi = 0)

Try taking the curl of both sides of equations 0.1 and 0.2 and see what you get...

Don't double post, ok?
