Prism, a transparent object surrounded by two intersecting planes that are not parallel to each other, used for splitting or dispersing light beams. Prism is a polyhedron made of transparent materials (such as glass, crystal, etc.). Is an important optical element. The plane on which light enters and exits is called the side, and the plane perpendicular to the side is called the main section. According to the shape of the main section, it can be divided into three prisms, right angle prisms, pentagonal prisms, etc. The main section of a prism is a triangle with two refractive surfaces. Their included angle is called the top angle, and the plane opposite the top angle is the bottom surface. According to the law of refraction, the light passes through the prism and deflects twice to the bottom. The included angle Q between the outgoing light and the incident light is called the deflection angle. Its size is determined by the refractive index n and incident angle I of the prism medium. When I is fixed, different wavelengths of light have different deflection angles. In visible light, the largest deflection angle is purple light and the smallest is red light.
