1. Hinged surfaces are trouble spots for Stealth designers because they can reflect radar beams. 2. Optical storage systems work by reflecting beams of laser light off of a rotating disk with a minutely pitted surface. 3. The Russian radar points up and its beam is reflected back to earth from fine meteor particles suspended in the atmosphere at high altitudes. 4. You can experiment with the properties of colors, filtering and reflecting colored beams of light. 5. The laser shoots horizontally out of the box into a mirror that reflects the beam straight down onto the spinning disc. 6. The mirror was supposed to work like an artificial moon, reflecting a beam of sunlight across the earth. |
