Data Table 4: Focal length (f) = -7cm Object Height (h.) = 2cm Object Distance (do) Image Distance (d;) Image Height (h,) Image Description (Check the correct word for each pair) 12cm Real Upright Enlarged Virtual Inverted Reduced 9cm Real Q Upright Enlarged Virtual O Inverted Reduced 6cm Upright Enlarged OL Virtual Inverted Reduced 2cm Real Upright Enlarged Virtual O Inverted Reduced Use the 12cm object and image distances to calculate the Use the focal length and the 6cm object distance to calculate the focal length. image distance. Did you get -7cm? Did you get the same as your measured d? Find the magnifications for each set of data. *Use the distance magnification equation: **Use the height magnification equation: do = 2cm do = 9cm do = 6cm do = 12cm Conclusions: 1. Where would the object need to be located to create the following types of images for CONVEX lenses. Use Table 1 and Table 2. Real images: Virtual images: Enlarged images: Reduced images: 2. Where would the object need to be located to create the following types of images for CONCAVE lenses. Use Table 3 and Table 4. Real images: Virtual images: Enlarged images: Reduced images: 3. For both types of lenses, what happened to the images when the focal length increased? 4. A 3-cm object is located at a distance of 20cm from a lens with focal length +5cm. What is the image distance? What is the magnification? What is the image height? Describe the image: ( Real ; Virtual ), ( Upright ; Inverted ), ( Enlarged ; Reduced ) for a ( convex ; concave ) lens. 5. A 9-cm object is located at a distance of 15cm from a lens with an image located at -3cm. What is the focal length? What is the magnification? What is the image height? Describe the image: ( Real ; Virtual ), ( Upright ; Inverted ), ( Enlarged ; Reduced ) for a ( convex ; concave ) lens
