Draw the ray diagram when the pencil object is outside the focal length of the convex lens. Label the principal axis, measured object length (cm), object point (P), measured image length (cm), image point (Q). The focal point (f) is already labeled for you. Indicate if the image is real or virtual. Indicate if the image is inverted or upright. Label the amount of magnification on your drawing.

3. Corrected_text: Where would the pencil (object) have to be placed on the principal axis so that the image distance is the same as the focal length?
