Question

Answer briefly.

Can we produce a pure electric or magnetic wave in space? Why?

Short/Brief Note
Advertisements

Solution

No.
In vacuum, an electric field cannot directly induce another electric field so a “pure” electric field wave cannot exist and same can be said for a “pure” magnetic wave.
