1. You have a thin lens of focal length 50 mm. a. The object is 100 mm to the left of the lens. Where is the image located (that is, what is the image distance q, including sign - express in millimeters)? Is the image real or virtual? What is the magnification? b. The object is 1 meter to the left of the lens. Where is the image located (that is, what is the image distance q, including sign - express in millimeters)? Is the image real or virtual? What is the magnification? c. The object is 20 mm to the left of the lens. Where is the image located (that is, what is the image distance q, including sign - express in millimeters)? Is the image real or virtual? What is the magnification?

You have a thin, diverging lens. If the value of q (the distance from the image to the mirror along the principal axis of the mirror) is -3.57cm and the distance of p (the distance from the object to the mirror along the principal axis of the mirror) is 17.16cm, what is the focal length of the diverging lens? Object Ray 1 Principal focal point Virtual image Diverging lens. Ray 1 Ray 3 Ray 2 Secondary focal point Note: Do not explicitly include units in your answer (it is understood the unit is cm). Enter only a number. If you do enter a unit, your answer will be counted wrong.

A converging lens is used to produce a virtual image that is erect and has a magnification of 3.90 with an object placed 14.3cm from the lens. a. What is the focal length of the lens? b. If the object distance is doubled, what type of image is produced? c. What is the new magnification?

Shown in the figure below is a system containing two lenses and an object. The focal lengths of the two lenses are f1 = -19 cm and f2 = 9.5 cm.
