A physicist's right eye is presbyopic (i.e., farsighted). This eye can see clearly only beyond a distance of 67 cm, which makes it difficult for the physicist to read books and journals. Find the focal length and power of a lens that will correct this presbyopia for a reading distance of 25 cm, when worn 2 cm in front of the eye focal length: cm diopters power Is this a converging or a diverging lens? converging diverging

The print in many books averages 3.50 mm in height
1. The print in many books averages 3.50 mm in height. How high is the image of the print on the retina when the book is held 30.0 cm from the eye? 2. A very myopic person has a far point of 20.0 cm. What power contact lens (when on the eye) will correct the distant vision? Assume the eyeglasses held 1.50 cm from the eyes. 3. A farsighted person has a near point of 50 cm rather than the normal 25...

8. Your nearsighted brother has a far point of 4 m and he wants to see an object 15 m away clearly Assume he will wear his glasses 2 cm in front of his eyes. What is the focal distance (in meters) of the glasses he needs? Hint: Draw a diagram of your brother, the glasses, the object and the image. Use the diagram to figure out whether the glasses have to be diverging or converging. 9. Consider question 8....

A farsighted man uses contact lenses with a refractive power of 2.20 diopters. Wearing the contacts, he is able to read books held no closer than 0.285 m from his eyes. He would like a prescription for eyeglasses to serve the same purpose. What is the correct prescription for the eyeglasses if the distance from the eyeglasses to his eyes is 0.030 m? in dipoters ??? not 1.67 A diverging lens (f1 = −13.5 cm) is located 23.0 cm to...

1. You do NOT need to show your work for this question. Be sure to include correct units, * signs, and sig. figs.! a. (4 pts.) You place a 30.0-cm-tall object 40.0 em away from a converging lens with a 50.0 cm focal length. Using our standard plus/minus sign comventions, find the following values: What is the position of the image? What is the height of the image? What is the magnification of the image? Is the image real or...

Could you please show all of the steps taken in solving the
problem and explain the process fully, using sentences/phrases (if
possible) to understand why those steps were taken and
why you got that answer.
Also could you please draw a diagram with any applicable
variables/values to help visualize the problem better.
Thank you in advance for all the help!
