Question

Diverging & Converging LENS

The same object (height = y) is placed at several different distances s to the left of the same lens (focal length = f). For each case, draw the 3 principal rays to locate the image. Then use the “thin lens” equations to calculate:

• the image height y' (in terms of y)

• whether the image is real or virtual

• the image distance from the lens s' (in terms of s and f)

• whether the image is upright or inverted

s=f Hint: This one has no image. s= }f s= if s= f

    An object of height 3.6 cm is placed at 24 cm in front of a diverging lens of focal length, f = -18 cm. Behind the diverging lens, there is a converging lens of focal length, f = 18 cm. The distance between the lenses is 5 cm. In the next few steps, you will find the location and size of the final image. Where is the intermediate image formed by the first diverging lens? Image distance from first lens...
