The light on the ceiling is 3.375m above the ground. When a thin lens is placed 25cm above the ground, a minified image of the light from the ceiling is formed on the ground. What is the primary focal length of the thin lens? If the image of the light formed is 8cm x 2.5cm in size, how large is the actual light?

A 25kg block is placed 2.7m above the ground on a frictionless ramp. At the bottom of a ramp there is an ideal spring. A. If the block is let go, how fast will the block be moving at the bottom of the ramp? B. The block runs into the spring and compresses the spring a total of .35m before coming to a stop. What is the spring constant of the spring? The block then slides back up the ramp....

You are to design a thin lens for eyeglasses that will have a focal length of 10 cm. You only have tools that will allow you to shape glass surfaces with the following radii for convex surfaces: 4, 8, 12, 16, 18, and 21 cm, and the following radii for concave surfaces 3, 6, 7, 10, 12 and 14 cm. The glass to be used has an index of refraction of 1.48. Determine a combination you can use to make...
