One end of a long glass rod (n = 1.50) is formed into a convex surface with a radius of curvature of magnitude 6.00 cm. An object is located in air along the axis of the rod. Find the image positions corresponding to object distancesof (a) 20.0 cm, (b) 10.0 cm, and (c) 3.00 cm from the convex end of the rod.

= A leaf of length his positioned d below. Leaf d 70.3 cm in front of a converging lens with a focal length of 34.0 cm. An observer views the image of the leaf from a position 1.26 m behind the lens, as shown in the figure 1.26 m (a) What is the magnitude of the lateral magnification (the ratio of image size to the object size) produced by the lens? (b) What angular magnification is achieved by viewing the image of the leaf rather than viewing the leaf directly?

Spherical mirrors. Object Ostands on the central axis of a spherical mirror. For this situation object distance is p, = +16 cm, the type of mirror is concave, and then the distance between the focal point and the mirror is 12 cm (without proper sign). Find (a) the radius of curvature r (including sign). (b) the image distance i, and (c) the lateral magnification m. Also, determine whether the image is (d) real or virtual, (e) inverted from object O or noninverted, and (f) on the same side of the mirror as O or on the opposite side. (a) Number Units (b) Number Units (c) Number Units (d) (e) (f)
