The Telescope and the Microscope Lab Phys 102 Manju Sogi & Alma Fuentes Abstract The purpose of this experiment is to build a microscope and telescope while finding their magnifying powers. Data Focal lengths of lenses Lens B 14.47cm Lens C 50 cm Lens D 5.39 cm Graphs N/A Sample Calculations Focal lengths 1/f= 1/p + 1/q Lens B =14.47 cm Lens C = 50 cm (given) Lens D = 5.39 cm Microscope Mtheo = -L*25/fo*fe -60*25/ 14.47*5.39 =-19.23 Mtheo = fo/fe Mexp = hi/ho Telescope 50/14.47= 3.45 cm 8.5/2.123 = 4cm % diff = V1- V2 / (V1 + V2 / 2) *100 = 3.45 – 4 / (3.45 + 4/ 2) * 100 = 10.1% Results Microscope Mtheo = -19.23 Telescope Mtheo = 3.45 Mexp = 4 % Error % diff = 10.1 % Questions Microscope 3a. The image that is seen through the lens is that of the object which was upside down. 1. In the refracting telescope 2 lenses are arranged so that the objective forms a real, inverted image of the distant object very near the focal point of the eyepiece. Therefore it’s objective’s focal length over the eyepiece’s focal length because the angular magnification is the ratio of the angular size seen with the telescope to the angular size seen with the unaided eye. 2. A prism and the phenomenon of total internal reflection can alter the direction of the image that’s seen therefore the object viewed seems altered and erect. 3. 1/f = 1/p + 1/q if p= infinity 1/p = 0 therefore 1/f = 1/q thus f= q 1/f= 1/f1 + 1/f2 Conclusion In conclusion, we found that our experimental magnification, 4 for the telescope was close to the theoretical magnification, 3.45. In addition, the experimental value for the microscope was close to the theoretical value as well. The percent difference was 10.1 which was fairly close to the actual values. Thus any human errors made during the experiment might have made that percent difference error. Grade 70/100
