Popis: Injection of a thin layer of solution at the boundary of a moving solvent is utilized to create a thin fluid sheet having an index of refraction greater than that of the surrounding medium. Conditions are such that light trapping is easily observed in the thin fluid sheet. Diffusion effects give rise to a concentration profile which is quadratic at the boundary. As a consequence of this quadratic dependence, an interesting hopping and refocusing of a trapped beam is observed as it traverses the fluid sheet. The observed phenomenon is readily modeled by use of the Navier Stokes equation and the diffusion equation.
