Imagine a light ray traveling from a vacuum (medium 1) into another medium containing an unknown substance (medium 2). When the light hits the interface between the two media, the initial angle of incidence is 40 degrees (measured from a line perpendicular to the boundary surface), and it is then refracted by an angle of 29 degrees (again, measured relative to a line perpendicular to the boundary surface). What is the speed of light (in units of meters per second)...
