An object with height of 5 cm is placed 15 cm in front of a convex lens with focal length 10cm. What is the height of the image formed by this lens?
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 sun is 150,000,000 kmkm from earth; its diameter is 1,400,000 kmkm. For a science project on solar power, a student uses a 24-cmcm-diameter converging mirror with a focal length of 51 cmcm to focus sunlight onto an object. This casts an image of the sun on the object. For the most intense heat, the image of the sun should be in focus.
What is the intensity of sunlight in the projected image? Assume that all of the light captured by the mirror is focused into the image.
Express your answer with the appropriate units.
