Let respectively b = (b(adsbygoogle = window.adsbygoogle || []).push({}); _{1}, b_{2}, b_{3}) and e = (e_{1}, e_{2}, e_{3}) denote the magnetic

and electric field in some medium. They are governed by Maxwell’s equations which look as follows:

(0.1) [tex]\partial[/tex]_{t}e = curl b

(0.2) [tex]\partial[/tex]_{t}b = − curl e

(0.3) div e = 0

(0.4) div b = 0.

Show that each b_{i}and each e_{i }satisfies thewave equation

([tex]\partial[/tex]_{t}^{2}- [tex]\Delta[/tex]) [tex]\varphi[/tex]=0
