Measure your near point by bringing this page up to the closest distance at which the image is still crisp—not the closest at which you can still read the letters, but the closest at which they remain sharp. (If you wear glasses or contacts, keep them on.) Measure the distance to determine your near point. What is your range of accommodation?

Two convex lenses of focal lengths 20 cm and 10 cm are placed 30 cm apart, with the lens with the longer focal length on the right. An object of height 2.0 cm is placed midway between them and observed through each lens from the left and from the right. Describe what you will see, such as where the image(s) will appear, whether they will be upright or inverted and their magnifications.

You put a 1.34-cm high candle 9 cm in front of a lens and you see an image with di = -6.09 cm. On your paper, draw: the lens (draw this as a diverging or converging lens based on the focal length) the optical axis the candle three rays from the object to the image. These rays should reach the lens traveling: parallel to the axis toward the center of the lens toward the focal point (note: for a diverging lens, this would be the focal point on the opposite side as the object) the image a box with the following information about the image: real or virtual upright or inverted magnified, reduced or same size In the space below enter the height of the image in centimetres. If it is inverted, the height will be negative.
