Experiment 10: Student name: Pre-lab section: 1)
Introduction: Explain the theory behind this experiment in a paragraph between 150 and 250 words. (2 Points)
Suppose you are using external resources; include the reference. It would be best if you had any relevant formulas and explanations of each term. You may use the rich formula tools embedded here. The theory behind this experiment is that lens of the type shown in this experiment has the property that when a beam of parallel rays passes through the lens the raised converge to a point F2 form a real image at that point. Such a lens is called the converging lens. Similarly rays passing through point F1 d0 = F Emerge from the lens as a beam of parallel rays. The points F1 and F2 are the first and 2nd focal points of the lens respectively. The value of the focal length of converging lens is positive. In a diverging lens the beam of parallel arrays incident on the this lens it diverges after refraction and appears to come from the second focal point F2 which is to the left of the lens, while the incident rays converging towards the first focal point F1 emerge parallel to the axis. The value of the focal length of diverging lens is negative. 2)
Hypothesis: In an If /Then statement, highlight the purpose of the experiment.
(1 point)
If the distance between the object and the lens is greater than the focal length would be larger. 3)
In a paragraph between 100 and 150 words, explain. What did you Learn In exp 10.1? What conclusion can you draw from the results of this lab assignment? (1 point)
The conclusion I can draw from this lab from what I learned is that the thin lens equation is 1 / F = 1 over d0 plus one over di. The magnification of a thins lens is m = H I over H0 equals negative di/d0. Hi and h0 are the sizes of the image and the object respectively. The value of the focal length of converging lens is positive. The value of the focal length of diverging lenses is negative. The image character size and position can also be determined by a graphical method called a principle ray diagram. 4)
In one sentence, compare the results of the experiment with your Hypothesis. (1 point)
My hypothesis was correct the larger the distance between the object and the lenses then the greater the focal point would be. Post-lab section: 5)

In a paragraph between 100 and 150 words, explain what you Learn. What conclusion can you draw from the results of this lab assignment? (2 points)
This lab is that telescope is used to view large objects at large distances. An astronomical telescope is constructed with two converging lenses: an objective and an eye piece. The objective lens form a real reduced image of the object. This image is the object for the I piece lens. Objects that are viewed with a telescope are usually so far away from the instrument that the first image is formed very narrowly at the second focal point of the objective lens. If the final image formed by eyepieces at Infinity, the first image must also be at the first focal point of the eyepiece. The distance between objective and eyepiece L is therefore the sum of the focal lengths of objective and eye piece. 9)
