134 When a ray of light enters the eye, it first meets the air-cornea surface and strikes it at an angle of incidence of 30 with respect to the perpendicular. The refractive index of the cornea is approximately 1.4.Calculate the angle of refraction.Calculate the angle of refraction if the person is swimming in water.You want the angle of refraction in the case of water to be the same as in the case of air. What should the new angle of attack be?[21st; 28; 22]

134 .. Quando un raggio di luce entra nell'occhio, dapprima incontra la superficie aria-cornea e la colpisce con un angolo di incidenta di 30 rispetto alla perpendicolare. L'indice di rifrazione della cornea e circa 1,4. . Calcola l'angolo di rifrazione. . Calcola l'angolo di rifrazione nel caso in cui la persona stia nuotando in acqua. . Vuoi che l'angolo di rifrazione nel caso dell'acqua sia lo stesso che nel caso dell'aria. Quale dovrebbe essere il nuovo angolo di incidenta? [215; 280; 22"]
