FIGURE 1.1 The wave motion of light.
The wavelength, a of the sine-curve is measured by the length of one such wave, i.e.,
by the distance from crest to crest, or from through to through.
The electric field E and the magnetic field H, are in free space always numerically equal
when measured in appropriate units. In free space, the energy per unit volume in an electric
field is E-187, and the energy per unit volume in a magnetic field is HⓇ1877. So the energy
W per unit volume in the electromagnetic wave field is
W = E2/87 + H²1811 = E2/471 = H2/470
(1.1)
can anybody tell how to solve this equation
