Set of equipment for carrying out 38 student experiments on optics. Comes with comprehensive student and instructor experiment manuals and instructions. In a tough plastic tray containing a foam insert with cut-outs for the equipment and featuring a transparent lid. The experiments are designed to be compact but still easy to see when set up and carried out on the supplied optical bench or the SEK base plate (1000789 / U8408035). In both cases, the optical components are attached in non-slip fashion by magnets. Supplied overlays designate where the components are to be placed. Note: The 1008530 SEK Optics is for operation with a mains voltage of 230 V (±10%), and the 1008531 set is for operation with a mains voltage of 230V (±10%).Features:Exleriments included:Propagation of light, light beams and raysTransparencyLight and shadowUmbra and penumbraReflection from a plane mirrorConcentration of light by a concave mirrorReflection and path of light for a concave mirrorReflection and path of light for a convex mirrorCharacteristics of the image from a plane mirrorWhen light passes from air into glass / Determination of refractive indexWhen light passes from glass into air / Determination of refractive indexDetermination of critical angle for total internal reflection (glass to air)Ray diagrams for a rectangular glass block, lawsRay diagrams for a glass prismTotal internal reflection inside a prismPath of light through a converging lensDetermination of focal length for a converging lensRay diagrams with parallel ray and ray through centre of lens (converging lens)Path of light through a diverging lensDetermination of focal length for a diverging lensRay diagrams with parallel ray and ray through centre of lens (converging lens)Path of light through a system of lensesImage Properties (converging lens)Image magnification and the lens equationImage aberrations with converging lensesFormation of images in the eyeShort-sightednessLong-sightednessAstigmatismCamerasSlide ProjectorsMicroscopesGalileo telescopeKepler's telescopeTerrestrial telescopeSeparation of light into a spectrumRecomposition of spectral coloursAdditive mixing of colours, complementary colours.
