Remove the rays from the simulation by clicking on them and then pressing Delete. Place a Point Source at (60,180) by clicking Point Source under Tools, then clicking the simulation at (60,180). Note that the location at which the rays converge is the same as it was using the principal ray method. This is, in fact, why we use the principal ray method: it generates the convergence point using comparatively few lines. As we know from Huygens's principal, every point...

We usually locate the image formed by an object by looking for
theintersection of just two of the rays coming from that object,
andwe usually choose these two rays to be as simple to draw
aspossible. In fact, all the rays coming from the object that
passthrough the lens must converge at the location of the image.
Inthis problem you will be asked to identify some of these
otherrays, which are not so simple to draw.

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...

Learning Goal: To become familiar with using the image of one instrument as the object of the next and tracing rays through a system of multiple instruments. Multiple optics refers to any system of more than one optical instrument through which light passes. Most devices related to optics, such as cameras, microscopes, and telescopes, contain multiple optics systems. In multiple optics, the image of one optical instrument becomes the object of the next one. Thus, in multiple optics problems, you...

Don't quite get questions 1-6
For lenses in combination, the image for the first lens is the object for the second. The ray tracing diagram below shows how the rays travel through the system from object to first image/second object and then to second image. The first ray trace gives the location and size of the first image. A second ray trace is performed to find where the second object (which is the first image) creates the second image. It...
