The end of a glass rod has the shape of a hemisphere of radius 3.2 cm. The hemisphere bulges outward. Point P is in the air along the optical axis at a distance of 9.3 cm in front of the glass rod. What is the image distance of a small object placed at point P? Let the indices of refraction nglass = 1.56 and nair = 1.00.

23 cm into the glass rod

11 cm in front of the glass rod

11 cm into the glass rod
