Description:This product uses 4 convex lenses arranged in an orderly line on the same line to understand the phenomenon of refraction when light passes through different media and interfaces. The convex lens is made using this principle and the combination of N convex lenses and convex-concave lenses can be made into a telescope. applicationrstand the principle of light refraction and its applications through experiments objective lens of the telescope and the main optical axis of the eyepiece coincide, and the focal points of the adjacent sides coincide at one point. The distance from the distant celestial body AB to the objective lens is much greater than the double focal length of the objective lens. According to the imaging law of the convex lens, the distance from AB’s image A’B’ to the objective lens is slightly larger than the focal length of the objective lens, and the distance to the eyepiece is smaller than the focal length of the eyepiece, so pass The eyepiece will see the enlarged image of A’B’age include:1 x DollaTek DIY Telescope experimental equipment science experiment early education
