Question

0. The vector wave equation is defined as,​

Answer 1

Answer:

derivatives of the other are [1, 2]:

∇ ∧ E = −µ0

∂H

∂t = iωµ0H = i

µ0

ε0

kH,

∇ ∧ H = J + ε0n2 ∂E

∂t = J − iωε0n2E = J − i

ε0

µ0

kn2E,

(1.3)

and the divergences are

∇ · (ε0n2E) = σ,

∇ · (µ0H) = 0, (1.4)

where J is the current density, σ the charge density, and ω = 2 π c/λ =

k/

√ε0µ0.

In the MKS system of units, ε0 = 107/4π c2 F m−1 andµ0 = 4π 10−7 H m−1.

The factor √µ0/ε0 has the units of an impedance and corresponds to 377 ,

the impedance of a vacuum.

Second answer is hope it help you

The wave equation is an important second-order linear partial differential equation for the description of waves—as they occur in classical physics—such as mechanical waves (e.g. water waves, sound waves and seismic waves) or light waves. It arises in fields like acoustics, electromagnetics, and fluid dynamics.
