Once we verify the law, we can use it with the simulation to demonstrate total internal reflection, a phenomenon important to fiber optic technology. In the last activity, we will work with the separation of colors by prisms and the creation of rainbows through a demonstration of the dependence of the index of refraction on the wavelength of light.

The exploration of light behavior through experiments such as verifying Snell’s Law, demonstrating total internal reflection, and observing spectral dispersion provides fundamental insights into optical physics and the behavior of light. These phenomena are integral to both theoretical understanding and practical applications in modern technology, particularly in fiber optics and spectroscopy.

Snell’s Law describes how light bends, or refracts, when transitioning between different media. Mathematically, it is expressed as n₁ sin θ₁ = n₂ sin θ₂, where n₁ and n₂ are the indices of refraction, and θ₁ and θ₂ are the angles of incidence and refraction respectively. Using the PHET Bending Light Simulation, students can visually verify this law by varying the incident angle and observing the corresponding refraction angles. Such empirical confirmation reinforces the understanding of how light behaves at interfaces and helps students develop intuitive grasping of index of refraction values and their relation to material properties.

Upon validating Snell’s Law, students can explore total internal reflection, which occurs when light attempts to pass from a medium with a higher index of refraction to one with a lower index at an angle greater than the critical angle. The critical angle can be calculated using the relation θ_c = arcsin(n₂/n₁). When this angle is exceeded, all incident light reflects internally rather than refracts outward, a phenomenon critical to the operation of fiber optic cables. Fiber optics depend on total internal reflection to transmit light signals over long distances with minimal loss, revolutionizing telecommunications and data transmission.

The experiment's final phase involves understanding how prisms separate white light into its constituent spectral colors, producing rainbows. This dispersion arises because the index of refraction varies with wavelength—shorter wavelengths (blue and violet) refract more than longer wavelengths (red). By demonstrating the dependence of the index of refraction on wavelength, students gain insight into the physical basis of phenomena like rainbows and the functioning of spectrometers. Such dispersion allows scientists to analyze the spectral composition of light sources, essential in fields such as astrophysics and chemical analysis.

In conclusion, these experiments enhance the comprehension of fundamental optical principles, illustrating both the wave nature of light and its interactions at interfaces. Verifying Snell’s Law, demonstrating total internal reflection, and observing dispersion not only deepen theoretical understanding but also underscore the practical significance of optics in technology and natural phenomena.
