In Part 4.2.2, you will determine the focal length of a convex lens by focusing on an object across the room. If the object is 10 m away and the image is 9.8 cm, what is the focal length? (Hint: use Lab Manual Equation 4.2: 1/ o+ 1/i= 1/f,convert m into cm) Suppose one estímated the focal length by assuming f = i. What is the discrepancy between this approximate value and the true value? (Hint: When the difference between 2 numbers is much smaller than the original numbers, round-off error becomes important. So you may need to keep more digits than usual in calculating the discrepancy.) cmkeep 1 digit after decimal point),

An object is placed 40 cm in front of a thin lens. If an image forms at a distance 120 cm from the lens, on the opposite side as the object, what is the focal length of the lens, in cm? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
