You have a concave (diverging) lens with a −30 cm focal length. The magnification produced by the lens for a particular object distance is m = 1/2 and you wish to decrease the magnification to m = 1/8. Determine the distance and direction (away from or closer to the lens) through which the object must be moved in order to accomplish this.

A concave lens has a focal length of -36 cm. Find the image distance and magnification that results when an object is placed 19 cm in front of the lens. (Use the proper sign convention for both quantities.) When an object is located 61 cm to the left of a lens, the image is formed 25 cm to the right of the lens. What is the focal length of the lens? An object with a height of 2.22 cm is...

An object is located to the left of a convex lens whose focal length is 38 cm . The magnification produced by the lens is m1 = 3.3. To increase the magnification to 4.5, should the object be moved closer to the lens or farther away? Farther away can you please Calculate the distance through which the object should be moved???
