{"product_id":"newton-disk-diam-200mm","title":"Newton Disk diam 200mm","description":"\u003cp\u003eNewton Color Disc for demonstrating that white light may be composed from all the spectral colors by rotation of multi color disc. Comprising of a disc 200 mm, mounted on metal stand and driven by belt with the help of driving wheel fitted with a handle, can be clamped on table.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cp\u003eDiameter approx. 200 mm – large enough for clear visual demonstration in a classroom\/lab.\nColour-segmented disk – divided into 7 segments (typically violet, indigo, blue, green, yellow, orange, red) around the circumference.\nSturdy stand\/mounting – the disk is mounted on a pillar or spindle that allows rotation, often with a base (wooden or metal) for stability.\nManual or hand-driven rotation – many models are operated by hand wheel or knob to spin the disk. (Some variants may offer motorised versions.)\nEducational optics demonstration – visually shows additive\/averaging mixing of colours via rapid motion (temporal optical mixing) and gives a tangible sense of how “white light” can result from all the spectral colours blended.\nDurable construction – typically disk made of tin sheet\/card or plastic, mounted on metal\/wood stand; designed for repeated classroom use.\u003c\/p\u003e","brand":"Kelsun Lab","offers":[{"title":"Default Title","offer_id":51370177528110,"sku":null,"price":150.0,"currency_code":"QAR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/1907\/2814\/files\/51iVoI5zzgL._AC_UF1000_1000_QL80.jpg?v=1764957026","url":"https:\/\/taalimiyah.com\/products\/newton-disk-diam-200mm","provider":"Taalimiyah","version":"1.0","type":"link"}
