✦ Synopsis

Study of electrohydcodynamic instabilities in thicker nematic liquid crystal samples (800-1200 pm) of MBBA is reported. An initial rise in the intensity of transmitted light immediately after the application of an electric field has been found to precede the attenuation of the transmitted beam due to the gradual development of hydrodynamic instability in the sample. The dependence of the relative dominance of the two relaxation phenomenon on the applied electric field 'intensity has been studied.
