Question

Problem 1: Ray tracing with a converging lens A 17 cm high object is located 50 cm away from a converging lens with a focal length of 30 cm. The drawing below is to scale (but is not necessarily at a scale of 1:1). A. Draw a ray diagram to find the image, including the height and orientation of the image: you only need to draw 2 of the special rays, but you can draw more if you'd like. Use a straightedge and be as accurate as possible. B. Use a ruler to measure the image location, using the appropriate sign to indicate whether it is a real or virtual image. Make sure that you scale your measured value appropriately. C. Use the thin lens equation to compute the image distance, and then compute the percent error of your measurement. D. Use a ruler to measure the image height, and then use it to find the linear magnification. Make sure that you scale your measured value appropriately.

Answer 1

I (1) Taking scale of 1:810 7.2 . (@) .. The measured value = 7.2 After scaling the image location is 719410-72 cm from lem. (C) The Leno maker's formula is given as. + : -4. given f = 30 cm, u = -50cm. .. Bo = + + st: too 37 V 75 cm : Fremon = 757221004. 100 . = 4%. (D) The measured value of image height = 2.5. After scaling the image height = 9.5*10 cm = 25 cm (red Magnification: Heightht of object : 7252-147. Scanned with CS CamScanner

P.S: There must be a difference in scale while sending the soft copy (i.e. picture) so the photocopy will not show proper scale. So I would suggest to draw yourself once more learning the steps from the solution.
