Question

Optics review D. A converging and diverging lens, each of focal length of magnitude 15.0 cm, are placed 50.0 cm apart (converging lens to the left), and a 5.0 cm tall object is placed 30.0 cm in front of the converging lens. a. Draw a diagram which shows the lenses, the object, the intermediate image, and the final image. This does NOT need to be a ray diagram! b. Determine position and height of the final image.

image formed by convex lens is real and inverted which will the image for the concave lens which is 20 cm infront of concave lens .also from this we can observe that object is inverted for the concave lens and image is virtual and erect and small in size to the object
