Hem estat provant com es modifica la imatge segons l’angle que formen aquests dos miralls. Ens han sortit imatges molt boniques. Les podeu veure clicant aqu\u00ed<\/a>. I sobretot, hem descobert perqu\u00e8 els angles que ens interessen s\u00f3n els de 180\u00ba, 120\u00ba, 90\u00ba, 72\u00ba, 60\u00ba…30\u00ba… Tot els que s\u00f3n una part exacta dels 360\u00ba de la circumfer\u00e8ncia.<\/p>\n
