A 2.0-cm-tall object is 20 cm to the left of a lens with a focal length of 10 cm. second lens with a focal length of 15 cm is 30 cm to the right of the first lens. a) Calculate the final image position and height using thin-lens equations. b) Use ray tracing to find the position and height of the final image. Do this accurately with a ruler or paper with a grid. Estimate the image distance and image height by making measurements on your diagram.

5. An 4 cm high object is placed 25 cm in front of a lens of focal length +20 cm. 60 cm past the first lens is a second lens of focal length +25 cm. a) Draw a ray diagram, showing (approx) relative positions of lenses, objects, and images b) How far past the 25 cm lens does the final image form? c) What is the size and orientation ( relative to the original object) of the final image?

1) A 12.0 cm tall object is placed to the left of a lens of unknown focal length. The lens creates an image to the right of the lens, as shown in the picture. Object a b) Image s Using a straightedge, locate the focal points of the lens. Mark these focal points with dots on the picture. Is this image real or virtual? Explain briefly. The magnification of the image is -0.75, and the object distance is 15.0 cm. Find both the image location d; and the focal length of the lens f.
