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...

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...

1.)
Parallel light rays pass through a concave lens as illustrated in
figure 1. Using the diagram, indicate the focal point of this lens.
2.) A convex lens has a focal length of 100 mm. The lens
produces an image from an object placed 50 cm from the lens.
Determine the distance from the lens to the image in the
magnification of the image.

You should see a sketch of an object, a thin, convex lens, and an image, with two light rays passing from one particular point on the object through the lens, to one particular point on the image, and beyond. The horizontal line stretching across the screen is called the "principle axis". The small "x" marks...
