to anwer Question 4 points

Data provided below
The magnitude of the lateral magnification is defined to be imi = Image Height = 4 Object Height h, 3) From geometry this can be shown to be equal to From ur measurements obtained for source-screen distance equal to 85 cm, compare the yo lateral magnification using each of the two relations above. Do this for the first position o the lens (the unprimed measurements) and then for the second position of the lens (the primed measurements) 4) For the simple magnifying lens, the perceived image is magnified. From your measurements, calculate your perceived magnification, equal to hlho, and compare that to e quation (5). Do the same for your partner's data. Questions (4 pts): 1) How do the values of the focal lengths found in the two methods compare? 2) How do the magnifications for the two different relations compare? 3) Explain why, for a given object-screen distance, there are two positions where the image is in focus. 4) Do the perceived magnifications of the simple magnifying lens agree with that of equation (5)? Pre-lab exercises: 1. What is the focal length of a magnifying glass of 3.0 X magnification for a relaxed normal eye? 2. What is the magnification of an astronomical telescope whose objective lens has a focal length of 70 cm and whose eyepiece has a focal length of 3.0 cm? What is the overall length of the telescope when adjusted for a relaxed eye? 3. A microscope uses an eyepiece with a focal length of 1.5 cm. Using a normal eye with a final image at infinity, the tube length is 17.5 cm and the focal length of the objective lens is 0.60 cm. What is the magnification of the microscope? aiyy no do
