"<span class="Apple-tab-span" style="white-space: pre;"></span>Nature
abounds with examples of vibrations and wave behavior. Interesting
designs in space are often produced when sound, light, or water waves
meet and combine. With the technique of computer simulation,
intriguing color images are obtained representing the oscillation
patterns. Of special interest are regions where the different shapes
appear reflected but the colors are interchanged," states Dr. Rosenberg, who for the <br>
