Calculate the length of a Kerr cell using carbon disulphide
required to produce half wave retardation for an applied voltage of
30kV. The electrodes of this cell have a separation of 1.5 cm. Is
this cell practical? Repeat the calculation, this time the carbon
disulphide being replaced by 4-cyanophenyl 4-pentylbenzoate. Use
values given in the notes. Is this cell practical?
Carbon disulphide CS2 3.5 × 10-12 cmV-2 .
4-cyanophenyl 4-pentylbenzoate 9537 × 10-12 cmV-2 at 63.9ºC.
GIVEN DATA
