Experiment 10 - 10.1: Lenses, 10.2: Telescope Student name: Juliana Dupuy Pre-lab section: 1) 10.1 Introduction: Explain the theory behind this experiment in a paragraph between 100 and 150 words . (1 points) A lens that converges causes a beam of parallel rays to converge at a certain location, producing an actual image at that location. At this point, the rays leave the lens as a beam of parallel rays. Convergent lenses have a positive focal length in every case. In a diverging lens, incident rays convergent toward the initial focal point emerge parallel to the axis, while a beam of parallel rays passing through the lens diverges after refraction and appears to originate from a focal point to the left of the lens. The focal length of a diverging lens is always negative. 2) 10.1 Hypothesis: In an If /Then statement, highlight the purpose of each experiment . (0.5 points) If a thin lens is placed at the front of an object, the focal length of the lens could be measured, and the picture characteristics could be examined. 3) 10.2 Introduction: Explain the theory behind this experiment in a paragraph between 100 and 150 words . (1 points) A telescope is an optical device used to view objects far away more clearly in its most basic form. Increasing the power of the telescope will get a better vision. A telescope uses two or more mirrors or lenses to gather more light and amplify it, giving it a higher resolution than the human eye can provide for seeing far-off things. The telescope has two convergent focal lengths: the long focal length object and the small focal length eyepiece. A real image will form in the focus point when the object is at infinity and the objective is pointed at it. With the eyepiece positioned in this way, one may examine the image produced by the objective at its focal point. L = f1 + f2 will be the telescope's length. A two-lens system's total magnification is the same as the sum of the magnifications of its individual lenses. 4) 10.2 Hypothesis: In an If /Then statement, highlight the purpose of each experiment . (0.5 points) If a telescope is properly built and used correctly, it will expand objects seen through it. Post-lab section: 5) 10.1 Discussion: In a paragraph between 75 and 150 words , explain what you learned from the results obtained in the experiment . What conclusion can you draw from the results of this lab assignment? (1 point) At the end of this experiment, I know more about the functions of converging and diverging lenses and how they could alter my perspective of a picture, for example, inverted versus erect, reduced versus enlarged. Using our light source device and two different lenses on a measured bench, I was able to measure the distances between the object and the lens as well as the distance between the picture and the lens. Both measurements are necessary to determine the focal point. This experiment

demonstrates how various lenses have unique characteristics and movements. Convergent lenses equally distribute light as it passes through them. It has been demonstrated that when convergent lenses are tilted at different angles of incidence, they have unique forms and diameters. Errors in lighting are possible. It's possible that the failing light caused a delay in the data collection procedure. 6) 10.1 Conclusion: In one sentence, compare the results of the experiment with your Hypothesis. Why? (0.5 point) The results of this experiment validated my theory by revealing the expected characteristics of the lenses. 7) 10.2 Discussion: In a paragraph between 75 and 150 words , explain what you learned from the results obtained in the experiment. What conclusion can you draw from the results of this lab assignment? (1 points) At the end of this experiment, I know that the magnification of the telescope can be found provided the focal lengths of the converging lenses are provided. To avoid erroneous results, it is imperative to shift the eyepiece to eliminate the parallax effect during picture or object viewing. It wasn't the most exact method, but I measured from the object (wall) to the lens (table) using three-meter sticks on the floor. Using the group optics bench and the two convergent lenses, I constructed my own "telescope" to examine the lenses magnification capabilities. This series of experiments illustrated the operation of telescopes and lenses. Any inaccuracies would be the result of human error, as these trials are only as exact as the human eye. 8) 10.2 Conclusion: In one sentence, compare the results of the experiment with your Hypothesis. Why? (0.5 point) The results of this experiment showed that the telescope's magnification could be predicted from the converging lenses' focal lengths.
