The standard equation for electromagnetic wave:
With the given equation:
E0 = 10 V/m
ω = 107
Therefore, c = vλ = ωλ/2π
The electric field of an electromagnetic wave in free space is given by
where t and x are in seconds and meters respectively. It can be inferred that
(i) the wavelength λ is 188.4 m.
(ii) the wave number k is 0.33 rad/m.
(iii) the wave amplitude is 10 V/m.
(iv) the wave is propagating along +x direction.
