- Will the focal length of a lens change when it is submerged in water? Explain.arrow_forwardA converging lens (n = 1.50) has radii of curvature of 2.50 cm and 5.00 cm; you will need to assign the correct signs. Determine the focal length of lens-1. A cup of Darjeeling (10 cm tall) is placed 5.00 cm in front of lens-1. Compute the position and magnification of the image. A diverging mirror, of radius 15 cm, is placed 20 cm to the right of the converging lens. Determine the (i) position, (ii) final magnification (and its image characteristics), and (iii) size of the final image. Draw a good ray diagram showing the location of the first and final image.arrow_forwardIf a lens is immersed in water, its focallength changes, as discussed in Conceptual Example 26-17.(a) If a spherical mirror is immersed in water, does its focal lengthincrease, decrease, or stay the same? (b) Choose the best explanation from among the following:I. The focal length will increase because the water will causemore bending of light.II. Water will refract the light. This, combined with the reflection due to the mirror, will result in a decreased focal length.III. The focal length stays the same because it depends on thefact that the angle of incidence is equal to the angle of reflection for a mirror. This is unaffected by the presence of thewaterarrow_forward
- The accommodation limits for a nearsighted persons eyes are 18.0 cm and 80.0 cm. When he wears his glasses, he can see faraway objects clearly. At what minimum distance is he able to see objects clearly?arrow_forwardConstruct Your Own Problem Consider a telescope of the type used by Galileo, having a convex objective and a concave eyepiece as illustrated in part (a) of Figure 2.40. Construct a problem in which you calculate the location and size of the image produced. Among the things to be considered are the focal lengths of the lenses and their relative placements as well as the size and location of the object. Verify that the angular magnification is greater than one. That is, the angle subtended at the eye by the image is greater than the angle subtended by the object.arrow_forwardDuring LASIK eye surgery (laser-assisted in situ keratomileusis), the shape of the cornea is modified by vaporizing some of its material. If the surgery is performed to correct for nearsightedness, how does the cornea need to be reshaped?arrow_forward
- A cataract-impaired lens in an eye may be surgically removed and replaced by a manufactured lens. The focal length required for the new lens is determined by the lens-lo-retina distance, which is measured by a sonar-like device, and by the requirement that the implant provide for correct distance vision. (a) If the distance from lens to retina is 22.4 mm, calculate the power of the implanted lens in diopters. (b) Since there is no accommodation and the implant allows for correct distance vision, a corrective lens for close work or reading must be used. Assume a reading distance of 33.0 cm, and calculate the power of the lens in the reading glasses.arrow_forwardIn Example 25.7, the magnification of a book held 7.50 cm from a 10.0 cm focal length lens was found to be 3.00. (a) Find the magnification for the book when it is held 8.50 cm from the magnifier. (b) Do the same for when it is held 9.50 cm from the magnifier. (c) Comment on the trend in m as the object distance increases as in these two calculations.arrow_forward(a) What is the focal length of a magnifying glass that produces a magnification of 3.00 when held 5.00 cm from an object such as a rare coin? (b) Calculate the power of the magnifier in diopters. (c) Discuss how this power compares to those for store-bought reading glasses (typically 1.0 to 4.0 D). Is the magnifier's power greater, and should it be?arrow_forward
