Answer 1

Answer:

energy density contained in an electromagnetic field, even a static one, is given by

Note that both of the above energy quantities depend quadratically on the fields E and B. To discuss the diffraction experiments

described above, it is useful to define the amplitude of an electromagnetic wave at each point in space and time r, t by the function

such that the intensity is given by

The function

will, in some later applications, have complex values. In such cases we generalize the definition of intensity to

where

represents the complex conjugate of

. In quantum mechanical applications, the function is known as the

wavefunction.
