Light Mediums: Transparent, Translucent, and Opaque

The video tutorial explains the three mediums of light: transparent, translucent, and opaque. Transparent objects, like clear glass, allow most light to pass through and do not cast shadows. Translucent objects, such as wax paper, allow some light to pass and cast faint shadows. Opaque objects, like cardboard and mirrors, block light completely and cast dark shadows. Mirrors, although opaque, reflect light instead of allowing it to pass through.
