Задача 40151.

In the apparatus for observation of the Kerr effect in nitrobenzene to the capacitor plates with length l = 5 cm and the distance between them is d = 2 mm a potential difference U = 1200V determine: 1) the difference of the refractive indices of the ordinary and extraordinary beams for monochromatic light having a wavelength 589 nm; 2) the phase difference and the path difference acquired rays for l. The Kerr constant for a given wavelength at a temperature of 20 C is equal to 2.42 * 10 ^ 10 cm ^ -2 * In.

Detailed solution with a brief record of the conditions, formulas and laws used in the solution, derivation of the calculation formula and answer.
