Packet 6: Bonus 15
The change in a material’s refractive index varies with the square of this quantity in the Kerr effect. For 10 points each:
[10m] Name this quantity that can be expressed as the negative derivative of voltage with respect to position and is typically measured in newtons per coulomb.
ANSWER: electric field [accept E-field]
[10h] The electric field at a certain distance from a point charge can be found by imagining a spherical shell and applying this law, which states that the electric flux through a surface is given by the enclosed charge divided by the vacuum permittivity.
ANSWER: Gauss's law for electricity [reject “Gauss's law for magnetism”]
[10e] The electric field is zero inside of these materials, as charge is concentrated on their surface. These materials in which electricity can flow freely are contrasted with insulators.
ANSWER: conductors
