1. The most common lens is a spherical lens. Describe the shape of a spherical lens.
2. Explain why light rays converge when passing through a double convex lens by describing the paths of three light rays; one along the optic axis and the other two parallel to the optic axis.
3. What happens to the image if half a converging lens is covered? Explain why this occurs.
4. What are the conditions necessary to form a virtual image using a converging lens?
5. What type of lens is used in a magnifying glass? Explain how to use the magnifying glass properly to see the largest possible image. Where should your eye be located and where should the object be located?

29. A lens with f = 4cm is used as a magnifying glass as shown below to image a small object of height 0.5 cm. The magnifying lens is being used by a person whose vision near point is 25 cm. The vision near point is the closest point the person can focus his eyes on a object without using a magnifying glass. (a) The object is initially 2.4cm from...

A thin converging lens of focal length 21 cm is located at the origin and its axis lies on the x axis. A point source of red light is placed at location (-33, 1, 0) cm. Where is the location of the image of the source? (Express your answer in vector form.) P = (-57.7,1.75,0) * cm Is it a real or a virtual image? It helps to draw a diagram and trace the "easy" rays.

A convex lens is a transparent instrument that uses refraction to bend and focus light from an object, forming a sharp image. We'll first investigate how the lens produces an image from a point source of light (a lamp). Select Screen at upper right, which makes the object a lamp and gives a black screen that can be dragged around. Select Many rays at upper left to see how the lens bends some of the rays of light from the...
