Additional Details

The large size of these optical components make this lens and prism set suitable for group work or even demonstration in front of the entire class. The set includes a variety of lenses and prisms, all of which are embedded with powerful neodymium magnets that allow for vertical demonstration. These magnets are strong enough to hold the components in place, making it easy for teachers and students to experiment with different configurations. The set also comes with a sturdy storage case, ensuring that the lenses and prisms stay organized and protected when not in use.
The set can be used to teach students about the critical angle, which is the angle at which light is refracted at the boundary between two materials in such a way that it is reflected back into the first material. This phenomenon is important in the fields of fiber optics and telecommunications, and can be easily demonstrated using the lenses and prisms in this set. By experimenting with different configurations of lenses and prisms, students can use Snell's law  and their understanding of optical components to learn about the relationship between the critical angle and the refractive indices of different materials.
