Lens L1 in Figure P23.45 has a focal length of 15.0 cm and is located a fixed distance in front of the film plane of a camera. Lens L2 has a focal length of 13.0 cm, and its distance d from the film p...

Q: An object is placed 15.0 cm from a first converging

An object is placed 15.0 cm from a first converging lens of focal length 10.0 cm. A second converging lens with focal length 5.00 cm is placed 10.0 cm to the right of the first converging lens. (a) Fi...

Q: An object placed 10.0 cm from a concave spherical mirror

An object placed 10.0 cm from a concave spherical mirror produces a real image 8.00 cm from the mirror. If the object is moved to a new position 20.0 cm from the mirror, what is the position of the im...

Q: A periscope (Fig. P23.5) is useful for

A periscope (Fig. P23.5) is useful for viewing objects that cannot be seen directly. It can be used in submarines and when watching golf matches or parades from behind a crowd of people. Suppose the o...

Q: A diverging lens (n = 1.50) is shaped

A diverging lens (n = 1.50) is shaped like that in Figure 23.25c. The radius of the first surface is 15.0 cm, and that of the second surface is 10.0 cm. (a) Find the focal length of the lens. Determin...

Q: The lens and the mirror in Figure P23.51 are separated

The lens and the mirror in Figure P23.51 are separated by 1.00 m and have focal lengths of +80.0 cm and -50.0 cm, respectively. If an object is placed 1.00 m to the left of the lens, where will the fi...

Q: The object in Figure P23.52 is midway between the lens

The object in Figure P23.52 is midway between the lens and the mirror, which are separated by a distance d = 25.0 cm. The magnitude of the mirror’s radius of curvature is 20.0 cm, an...
