Question

Answer the following about electromagnetic fields in matter, for 10 points.
[10e] In matter, Maxwell’s equations are formulated with the H field replacing this field. This field only exerts a force on moving charged particles.
ANSWER: magnetic field [or B field]
[10m] This type of charge is the source of the polarization in matter. This type of charge represents atoms or molecules that become dipoles in the presence of an external electric field.
ANSWER: bound charge
[10h] In media for which the polarization is a nonlinear function of the electric field, this effect can occur. In this effect, some of the energy of a propagating electromagnetic wave is converted into a wave with twice the frequency.
ANSWER: second harmonic generation [accept SHG; prompt on frequency doubling or sum-frequency generation or harmonic generation]
