A student in a physics classroom measured the distance from a convex lens (focal length of 4cm) to the object as 20 centimeters. The distance from the lens to the image projected on a screen is 5 centimeters from the lens. What is the magnification of the image?The image would be ¼ as tall as the object and upright.The image would be ¼ as tall as the object and upside down.The image would be 4 times larger than the object and upright.The image would be 4 times larger than the object and upside down.
