Path of Light
Operation: Turn the "Adjust" handwheel to change the angle of the optical elements and observe the path changes of the light passing through them. Function Overview: The exhibit consists of 8 types of optical elements: concave and convex lenses, concave and convex mirrors, right-angle prisms, wedge prisms, pentaprisms, and parallel glass plates, along with a laser light source and an operating handwheel. It demonstrates light divergence, convergence, reflection, refraction, and translation, thereby helping to understand the characteristics of optical elements. Light travels in a straight line in the same uniform medium. However, when light travels from one medium to another, refraction or reflection occurs at the interface between the two media. The exhibit consists of 8 types of optical elements: concave and convex lenses, concave and convex mirrors, right-angle prisms, wedge prisms, pentaprisms, and parallel glass plates, along with a laser light source and an operating handwheel. When parallel light rays travel from air to the optical elements, the light path changes. This demonstrates light divergence, convergence, reflection, refraction, and translation, thereby helping to understand the characteristics of optical elements. Scientific Principle: Due to the shape of the lenses and differences in refractive index, light undergoes refraction, diffraction, and other phenomena, presenting distinctive propagation paths. Concave lenses diverge light, while convex lenses converge light. When parallel light passes through these two types of lenses, significant changes in light direction can be observed. Parallel glass lenses do not change the direction of light but cause a slight displacement of the light, because the intersection points of the light with the lens surfaces differ when entering and leaving the lens. Triangular prisms can decompose white light into a spectrum of different colors, while wedge prisms can deflect light.
