f=+2cm 0 1 3 5 7 9 11 13 15 (cm) An object is placed 3 cm to the left of a convex lens of focal length f= 2 cm, as shown above. (a) Sketch a ray diagram on the figure above to construct the image. Use a ruler! (b) Use the lens equation to calculate the image distance. (c) Calculate the ratio of the image size to object size (use the lens equation). (d) State whether the image is real or virtual.J=-3cm 0 1 3 7 9 11 13 15 (cm) The converging les is removed and a concave lens of focal length f= -3 cm is placed as shown above. (e) Sketch a ray diagram on the figure to construct the image. (f) Calculate the distance of this image from the lens (use the lens equation). (g) Calculate the ratio of the image size to object size (use the lens equation). (h) State whether the image is real or virtual.f = +2cm f=-3cm + 0 5 7 9 11 13 15 (cm) The two lenses and the object are now placed as shown above. (i) Construct a complete ray diagram to show the final position of the image produced by the two-lens system. (j) State whether the image is real or virtual
