Q: A parallel beam of light enters a glass hemisphere perpendicular to the

A parallel beam of light enters a glass hemisphere perpendicular to the flat face, as shown in Figure P23.53. The radius of the hemisphere is R = 6.00 cm, and the index of refraction is n = 1.56. Dete...

Q: Two rays traveling parallel to the principal axis strike a large plano

Two rays traveling parallel to the principal axis strike a large plano - convex lens having a refractive index of 1.60 (Fig. P23.54). If the convex face is spherical, a ray near the edge does not pass...

Q: To work this problem, use the fact that the image formed

To work this problem, use the fact that the image formed by the first surface becomes the object for the second surface. Figure P23.55 shows a piece of glass with index of refraction n = 1.50 surround...

Q: Consider two thin lenses, one of focal length f1 and the

Consider two thin lenses, one of focal length f1 and the other of focal length f2, placed in contact with each other, as shown in Figure P23.56. Apply the thin - lens equation to each of these lenses...

Q: An object 2.00 cm high is placed 40.0

An object 2.00 cm high is placed 40.0 cm to the left of a converging lens having a focal length of 30.0 cm. A diverging lens having a focal length of -20.0 cm is placed 110 cm to the right of the conv...

Q: A “floating strawberry” illusion can be produced by two parabolic

A “floating strawberry” illusion can be produced by two parabolic mirrors, each with a focal length of 7.5 cm, facing each other so that their centers are 7.5 cm ap...

Q: A person spear fishing from a boat sees a stationary fish a

A person spear fishing from a boat sees a stationary fish a few meters away in a direction about 30° below the horizontal. To spear the fish, and assuming the spear does not change direction when it e...

Q: Figure P23.59 shows a converging lens with radii R1 =

Figure P23.59 shows a converging lens with radii R1 = 9.00 cm and R2 = -11.00 cm, in front of a concave spherical mirror of radius R = 8.00 cm. The focal points (F1 and F2) for the thin lens and the c...

Q: A dentist uses a mirror to examine a tooth that is 1

A dentist uses a mirror to examine a tooth that is 1.00 cm in front of the mirror. The image of the tooth is formed 10.0 cm behind the mirror. Determine (a) The mirror’s radius of curvature and (b) Th...

Q: Find the object distances (in terms of f) for a

Find the object distances (in terms of f) for a thin converging lens of focal length f if (a) The image is real and the image distance is four times the focal length and (b) The image is virtual and t...
