{"product_id":"bremsella-bremsstrahlung-pixel-sticker","title":"Bremsella – Bremsstrahlung (Braking Radiation) Physics Sticker","description":"\u003cp\u003eWhere do X-rays come from? Bremsella is an electron swerving past a nucleus. Any accelerating charge radiates, and for slow charges the Larmor formula gives the power, P = q²a²\/(6πε₀c³), so doubling the acceleration quadruples it. Bremsstrahlung, German for braking radiation, gives an X-ray tube its continuous spectrum as fast electrons stop in the metal target. A 3\" pixel-art sticker; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"2\" × 2\" \/ White","offer_id":50654967922791,"sku":"79479569673736368409","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3\" × 3\" \/ White","offer_id":50586281345127,"sku":"13276496469983768645","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4\" × 4\" \/ White","offer_id":50654967955559,"sku":"15616467300691629978","price":8.99,"currency_code":"USD","in_stock":true},{"title":"6\" × 6\" \/ White","offer_id":50654967988327,"sku":"21097836869309431439","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/2256907515648970634_1200.jpg?v=1793667264","url":"https:\/\/pixelatedphysics.com\/ja\/products\/bremsella-bremsstrahlung-pixel-sticker","provider":"Pixelated Physics","version":"1.0","type":"link"}
