Use Maxwell's Equations to derive a decoupled set of wave equations for electric and magnetic fields in a linear, homogeneous, isotropic media characterized by (µ, ε, σ) in the absence of sources. Then modify these equations to describe waves propagating in free space.
Show all work, please
Also free space means the air is a perfect dielectric. So conductivity is zero. (sigma=0) I have done that part too in the above.
Do put a comment if you need anything else.
Hope this helps.
Do give a like if you like the answer. It'll encourage me to write more quality answers.
