 P: 203 Dielectric Sphere in Time Varying Field Hi, If I have a spatially uniform field whose magnitude is changing in time (say $\vec{E}=E_o\sin(\omega t)\vec{k}$) and I place a dielectric in this field, will the perturbation of the field have the same frequency? That is, will the resultant field have a frequency $\omega$?
