Are you wanting a visualisation of the beam of light in the space
between the cube and the floor, or just the effect on the surface? If
the latter, radiosity is sufficient. If the former, you need to add a
scattering media surrounding the scene. At this point, the light needs
its photons checkbox ticked, the cube needs to be the target, and the
floor needs collect set to 'on'. Past that is a lot of fiddly
