[br][br]Per utilizzare il [b]microscopio[/b], bisogna porre l'oggetto che si vuole osservare appena al di là del fuoco dell'obiettivo. [br]Nel microscopio si forma un'immagine virtuale ed ingrandita.[br][br]Il [b]cannocchiale[/b] serve per osservare oggetti molto lontani. L'immagine rilevata è reale, capovolta e rimpicciolita e si forma in corrispondenza del fuoco dell'obiettivo.[br]Il rapporto tra gli angoli sotto cui l'occhio vede l'immagine con o senza cannocchiale si chiama [color=#ff0000]ingrandimento angolare.[br][/color]Se osserviamo la Luna al cannocchiale, sulla nostra retina si forma un'immagine più grande di quella che si forma guardandola a occhio nudo.[br][br][img]https://www.bing.com/th?id=OIP.STnqLUcWnVmuR4U-2EjvfAHaFj&w=288&h=215&c=7&o=5&pid=1.7[/img]
