Verified Answer

The electric field associated with an electromagnetic wave in certain ...

Given:

Therefore, the propagating vector

Therefore, the velocity of wave in medium.

Since, k is real so it can’t be lossy dielectric. Inside A perfact conductor

will be zero.
Velocity is less than c so the medium is dielectric.
