- Naiya wears glasses to correct her nearsightedness. The lenses have a power of Pi -2.50 D, and they are just powerful enough to allow Naiya to clearly focus on distant objects (i.e., objects located at infinity). Unfortunately, her glasses have gone missing, so today she is forced to wear her backup pair. The backup pair has a weaker prescription, but otherwise the two pairs of glasses are identical. Using the backup pair, she is only able to clearly focus on objects if they are closer than = 4.0 m from the lenses. What is the power P2 of the lenses in her backup pair? (Hint: your far point doesn't change when you take off your glasses.) Make sure that your representation indicates all the relevant details of the problem, such as: im- age distance, object distance, far point, lens-eye distance, lens shape, etc.An object measures 4cm high above the axis of an optical system consisting of a 2-cm aperture stop and a thin convex lens of 6-cm focal length and 5-cm aperture. The object is 14 cm in front of the lens and the stop is 2.50cm behind the lens. Determine the position and size of the entrance and exit pupils, as well as the image. Sketch the chief ray and the two extreme rays through the optical system, from the top of the object to its conjugate image point.Your telescope has a 850-mm-focal-length objective and a 22 mm -focal-length eyepiece. One evening you decide to look at the full moon in (Figure 1), which has an angular size of 0.52 ∘ when viewed with the naked eye. What angle (in degrees) does the image of the moon subtend when you look at it through your telescope? Suppose you decide to take a photograph of the moon using your telescope. You position a CCD detector so that it captures the image produced by the objective lens. What is the diameter of that image?

How far to the left of the first lens should the object be positioned? B) What is the overall magnification?A nearsighted person has a far point of 25.3cm and is prescribed contact lenses to correct her vision. What lens strength (a.k.a., lens power), in Diopters, should be prescribed? Give your answer using the usual convention of positive values for converging lenses and negative values for diverging lenses.
