You place a small lego figure 10.0 cm away in front of a thin convex lens with focal length 5.0 cm. What is the magnification (only magnitude)?

A slide projector needs to create a 88-cmcm-high image of a 2.0-cmcm-tall slide. The screen is 340 cmcm from the slide. What focal length does the lens need? Assume that it is a thin lens. Express your answer with the appropriate units. Enter positive value if the lens is converging and negative value if the lens is diverging.   How far should you place the lens from the slide? Express your answer with the appropriate units.

You use a lens to form an image. The object is 50 cm from the lens and the image is formed at a position of -14 cm. What is the focal length of your lens? f = cm What is the magnification of the lens? m = Is the image formed real or virtual? --- Is the image upright or inverted? Are you using a converging lens or a diverging lens?

= 3. A 15 cm tall object sits 80 cm to the left of a converging lens with a focal length of fi 30 cm. There is a second converging lens with a focal length of f2 = 20 cm sitting 60 cm to the right of the first converging lens. dige de a. Where is the image from the first lens formed? (find di1) f₁ = 30 cm do = 80cm di = ? C. -14 1-do₂ 'वे di = [130 - 50 ] = 48 cm to the right of lens 1 = b. What is the object distance for the second lens? (find doz) f₂ =20 cm do=48 cm di = ? Where is the final image formed? (find diz) do d. What is the distance between the original object and the final image? What is the overall magnification for this two-lens system? f. What is the height of the final image? (find hi2) 2
