An object, O, is placed 18 cm from the center of a converging lens of focal length, f= 6 cm as shown.
O F F
(a) On the illustration, sketch a ray diagram to locate the image.
(b) Is the image real or virtual? Explain your answer.
(c) Using the lens equations, compute the image distance.
(d) Calculate the Height of the image.

There is no illustration and we don't draw sketches.

I assume you know the lens equation, so use it to do part (c)

1/Do + 1/Di = 1/f

The image is real if Di, the image distance, is positive

For (d), the magnification is Do/Di
