| REFRACTION & TOTAL INTERNAL REFLECTION OF LIGHT OUT FROM A GLASS SLAB | |
Change the relative density of glass with respect to air, and observe how the light beam refracts as it leaves the glass and emerges into the air. Change the relative density of glass until you observe Total Internal Reflection

Change the angle of incidence, and observe how the light beam refracts as it leaves the glass and emerges into the air. Change the angle of incidence until you observe Total Internal Reflection.

When you increase the density of glass, does the angle of incidence needed to achieve total internal reflection increase or decrease?
