Details

Divide light into colour instantly! High-quality 4-inch (10 cm) right-angle acrylic prism divides white light into a colourful spectrum. Excellent for optics and physics studies. Includes a fun and informative guide book. Dimensions: 10 x 4. 3 x 3. 2 x 3. 2 cm. It'll refract light into a spectrum if there's a bright beam, e. g. from the Sun or a projector (such as lamp light focussed through a lens). The source should be as bright as possible but also small, ideally passing through a narrow slit, to get the clearest colours. If the source is big there'll effectively be several overlapping spectra, recombining to white (or off-white). You can get better spectra by using diffraction grating - its a transparent film with thousands of invisible parallel grooves. We strongly recommend our Rainbow Spectrum kit, which contains a glass prism, some diffraction grating, a lens, a LED lamp, detailed instructions, and all you need to discover how to make the best spectra. Although no one knows who invented the prism, Sir Isaac Newton first studied prisms in 1666. He passed sunlight through a prism and called the band of separated colours a 'spectrum', which means 'ghost of light'. Sir Isaac Newton was the first to prove that white light was in fact made up of different colours.
