3. A glass rod is 75.0 cm long and is surrounded by air. One end of the rod has a spherical surface that can be used to form an image. The index of refraction of the glass is 1.57. An object 3.50 mm tall is placed inside the glass on the axis of the rod, 36.0 cm from the spherical surface. The image formed is in the rod, 50.0 cm from the spherical surface. (a) What is the radius of curvature of the spherical surface at the end of the rod? Is the center of curvature in the glass or in the air? Justify your answer. (b) What is the height of the image? Is the image noninverted or inverted? Justify your answer.
