Science Buddies: Using Laser Pointer to Measure Data Track Spacing on C Ds, Dv Ds
You've probably noticed the colorful patterns "reflecting" from the shiny surface of a CD disk. What you are seeing is actually diffraction of white light, and the rainbows of color are diffraction patterns. In this project you'll learn...

Science Buddies: Centripetal Force
What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat. It works because of something called centripetal force and it does much more than make a great roller coaster. In this...
