Answer:
In these formulas, it is useful to understand which variables are parameters that specify the nature of the wave. The variables Eâ‚€ and Bâ‚€ are the amplitudes of the electric and magnetic fields.
Explanation:
Generally, the variables that specify the nature of the wave are:
(1) The amplitude of the electric field, designated as Eâ‚€, and
(2) The amplitude of the electric field, designated as Bâ‚€.
