Il proiettore per diapositive — costruzione ottica (problema 1x3)
Quesito a risposta aperta (Quesito uno X tre, punti).
Il proiettore per diapositive proietta immagini su uno schermo. La diapositiva (“oggetto”) è illuminata da dietro; la luce attraversa una lente convergente e raggiunge lo schermo. L’immagine è reale e capovolta. Lo schema ottico (unità arbitrarie) mostra l’oggetto (con base sull’asse ottico), la lente convergente con centro O, l’asse ottico, e i due fuochi (lato oggetto) ed (lato immagine).
Schema ottico (unità arbitrarie): asse ottico orizzontale, lente in O, fuochi a e a ; oggetti sul lato negativo con i raggi tracciati e le immagini dal lato opposto.
Promemoria: i raggi da uno stesso punto convergono in un punto dopo la lente; il raggio per il centro O non viene deviato; i raggi paralleli all’asse passano per il fuoco; distanza focale .
a) A quale distanza da O deve porsi l’oggetto perché l’immagine si formi in una certa posizione (leggere dal grafico)? b), c) Analoghe, per altre posizioni dell’immagine. d) Disegna l’immagine se l’oggetto è in posizione unità. e) Se lo schermo è a unità dalla lente, dove va posto l’oggetto? f) Spiega perché, se l’oggetto è posto sul fuoco , non si forma immagine nitida per nessuna posizione dello schermo. g) Compila la tabella con (oggetto-lente), (immagine-lente) e il rapporto . A cosa corrispondono questi rapporti? h) Compila la tabella con (oggetto-fuoco) e (immagine-fuoco). Quale relazione tra le due distanze? i) Se l’oggetto è a unità dalla lente, dove va posto lo schermo e quanto è grande l’immagine?
