How Does the Bending Light Simulation Work?
Exploring Refraction and Snell’s Law
At the core of the PhET bending light simulation is the phenomenon of refraction — the bending of light as it passes from one medium to another with a different refractive index. The simulation allows users to adjust the angle at which light enters a new medium and observe how the light ray bends.
By changing materials such as air, water, or glass, learners can see Snell’s Law in action, which mathematically relates the angle of incidence to the angle of refraction based on the refractive indices of the two media.
Reflection and Total Internal Reflection
Besides refraction, the simulation also demonstrates reflection, where light bounces off a surface, and total internal reflection, which occurs when light attempts to pass from a denser to a less dense medium at a steep angle, causing it to reflect entirely within the original medium.
Key Features and Tools in the Simulation
Adjustable Angles and Mediums
Users can interactively change the angle of incoming light and select different materials to see how these factors influence light’s path. This feature helps reinforce the relationship between variables in optics.

By adjusting these variables, users can see firsthand how light bends when it enters a new medium, such as water or glass.
The Role of Refractive Index
The refractive index of a material is a measure of how much light slows down and bends as it passes through that material. In the PhET simulation, users can experiment with different materials, each with its own refractive index. For example, light traveling from air (refractive index ~1) into water (refractive index ~1.33) will bend towards the normal, while light traveling from water to air will bend away from the normal. This interactive experience helps users grasp the concept of refractive index and its impact on light behavior.
