Unformatted text preview: E VALUATE : When and For the mobile home y / s is smaller so a larger f is needed. Note that m is very small; the image is much smaller than the object. 34.49. I DENTIFY : Use Eqs.(34.16) and (34.17) to calculate s and (a) S ET U P : E XECUTE : (b) E VALUATE : The lens allows the object to be much closer to the eye than the near point. The lense allows the eye to view an image at the near point rather than the object. 34.51. I DENTIFY : The thin-lens equation applies to the magnifying lens. S ET U P : The thin-lens equation is . E XECUTE : The image is behind the lens, so . The thin-lens equation gives , on the same side of the lens as the ant. E VALUATE : Since , the image will be erect. 25-1...
