Cream sand on deep navy within a fine mustard frame, it is sound made visible.\u003c\/p\u003e\n\u003cp\u003ePart of our Waves set in the Poster Kingz Puzzle \u0026amp; Science range. The fact behind the art: Sand collects on the nodal lines of a vibrating square plate. This pattern is the real mode cos(3 pi x) cos(7 pi y) - cos(7 pi x) cos(3 pi y) = 0. Ernst Chladni published these sound figures in 1787. Every design is drawn in code from the real data, so the details are right, then printed in our modern palette of cream, navy, terracotta, mustard and teal.\u003c\/p\u003e\n\u003ch3\u003eProduct details\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eExclusive Poster Kingz design\u003c\/li\u003e\n  \u003cli\u003eAvailable in A5, A4, A3 and A2 unframed sizes\u003c\/li\u003e\n  \u003cli\u003eAlso available framed in A5, A4 and A3, ready to hang straight out of the box\u003c\/li\u003e\n  \u003cli\u003ePrinted on premium quality paper stock\u003c\/li\u003e\n  \u003cli\u003eDesigned and printed in the UK by Poster Kingz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSee the rest of the set in our \u003ca href=\"\/collections\/science-posters\"\u003eScience Posters\u003c\/a\u003e collection, or browse the whole \u003ca href=\"\/collections\/puzzle-science-posters\"\u003ePuzzle \u0026amp; Science Posters\u003c\/a\u003e range.\u003c\/p\u003e","brand":"Poster Kingz","offers":[{"title":"A5 (unframed) 5.8 × 8.3 in","offer_id":58255684075902,"sku":null,"price":7.99,"currency_code":"GBP","in_stock":true},{"title":"A4 (unframed) 8.3 × 11.7 in","offer_id":58255684108670,"sku":null,"price":9.99,"currency_code":"GBP","in_stock":true},{"title":"A3 (unframed) 11.7 × 16.5 in","offer_id":58255684141438,"sku":null,"price":14.99,"currency_code":"GBP","in_stock":true},{"title":"A2 (unframed) 16.5 × 23.4 in","offer_id":58255684174206,"sku":null,"price":22.99,"currency_code":"GBP","in_stock":true},{"title":"A5 Framed","offer_id":58255684206974,"sku":null,"price":19.99,"currency_code":"GBP","in_stock":true},{"title":"A4 Framed","offer_id":58255684239742,"sku":null,"price":24.99,"currency_code":"GBP","in_stock":true},{"title":"A3 Framed","offer_id":58255684272510,"sku":null,"price":29.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0695\/8989\/3410\/files\/chladni-figure-print-sound-wave-physics-science-poster-1.jpg?v=1792269618","url":"https:\/\/posterkingzuk.com\/products\/chladni-figure-print-sound-wave-physics-science-poster","provider":"Poster Kingz","version":"1.0","type":"link"}
