Aquest mat\u00ed els alumnes de sis\u00e8 hem experimentat dues de les propietats de la llum “la refracci\u00f3 i la reflexi\u00f3”; mitjan\u00e7ant 4 materials: dos gots transparents, aigua, llet i sobretot un l\u00e0ser que ens ha fet de llum.<\/p>\n

Tots nosaltres hem pogut veure en primer lloc a la refracci\u00f3 de la llum a trav\u00e9s del l\u00e0ser i un got ple d’aigua, doncs quan enfoc\u00e0vem amb el l\u00e0ser la propagaci\u00f3 de la llum seguia viatjant en l\u00ednia recta per\u00f2 la imatge es distorsionava degut a que la llum ha viatjat a trav\u00e9s de 2 medis diferents (l’aire i l’aigua), a les dues velocitats s\u00f3n diferents, per aix\u00f2 hem pogut comprovar el fenomen de REFRACCI\u00d3<\/strong>.<\/p>\n

Tot seguit hem afegit llet a l’aigua, i la llum ha canviat de direcci\u00f3 autom\u00e0ticament, doncs al xocar amb la llet que \u00e9s opaca, el sentit de la llum ha variat i per aix\u00f2 hi ha hagut una REFLEXI\u00d3\u00a0<\/strong>de la llum, fenomen que passa quan la llum que es propaga en l\u00ednia recta topa amb un material opac i REFLECTEIX.<\/p>\n
