Does the dielectric constant changes as the voltage is applied in every dielectric material?

As the voltage is applied at both sides of the dielectric material(ex. front surface +5V and rear surface 0V), the energy is stored in the material, right? I heard it's...

Electron leaving the atom

From the photoelectric effect, we know that a photon can kick an electron outside the atom if it has the right amount of energy ($E_{gamma} geq W_0$). On the...

If virtual particles aren't real, then why do their masses correspond to those of real particles?

From all my searching it seems like the most common explanation of virtual particles is that they are merely internal lines in Feynman diagrams and therefore just a convenient pictoral...
