Amb el grup de F\u00edsica de 1er de Batxillerat, hem treballat l’\u00f2ptica de l’ull, per entendre millor com funcionen les lents, la llum, i relacionar aquest aprenentatge amb el funcionament del nostre propi cos.<\/p>\n

Per fer-ho, hem disseccionat un ull de vaca. Hem observat la seva morfologia, l’hem obert per veure la retina i per extreure’n el cristal\u00b7l\u00ed, que \u00e9s la lent que hi ha dins l’ull i que ens permet enfocar els objectes del nostre entorn.<\/p>\n

Hem comprovat com el cristal\u00b7l\u00ed t\u00e9 una dist\u00e0ncia focal d’uns tres cent\u00edmetres, coincident amb el di\u00e0metre de l’ull, i que, en observar objectes a trav\u00e9s seu, es veuen les imatges capgirades.<\/p>\n

Les imatges que esteu a punt de veure poden ferir la sensibilitat dels usuaris.<\/em><\/p>\n
