1. The problem statement, all variables and given/known data The focal length of the diverging lens is 74 cm. If an object with height h = 0.6 cm is located at d = 37 cm, what is the height of the image? 2. Relevant equations Thin-Lens Equation: (1/do)+(1/di)=1/f Magnification Equation: m=-di/do 3. The attempt at a solution I know that first I need to find the distance of the image, di. To do this I took: 1/[(1/74cm)-(1/37cm)]. From this I got -74cm. Next, I plugged this value into the Magnification equation: -(-74cm)/(37cm). From this I recieved a value of 2. Therefore the image should be 1.2 cm tall. When I entered this answer it was incorrect. I also know this is incorrect because images from a convex lens must be upright, reduced in size, and virtual. Can anyone help me out on where I am going wrong here?
