This quantity is directly proportional to the electric field by the Pockels effect. For 10 points each:
[10e] Name this dimensionless quantity, which shows how much light bends in a medium. This quantity can be calculated by taking the ratio of the speed of light in two different media.
ANSWER: refractive index [or index of refraction; prompt on n]
[10m] Unlike the Pockels effect, this effect asserts a linear relationship between the refractive index and the square of the electric field. This effect induces birefringence in some materials.
ANSWER: Kerr effect
[10h] To assess the dispersion of light in materials, this empirically derived equation states that vacuum wavelength is related to the refractive index. This equation is a modified version of Cauchy’s transmission equation.
ANSWER: Sellmeier equation
