An object is located 30 cm to the left of a converging lens whose focal length is 50 cm. (a) Draw a ray diagram to scale and from it determine the image distance and the magnification. (b) Use the thin lens and magnification equations to verify your answer to part (a).
I am stuck on this problem when I try to draw the ray diagram. What is stumping me is the object is in front of a focal length to the left. I am not sure how I am supposed to draw it properly. The steps in the book are not helping me at all.
