The discovery of this incredible phenomana in light allows us to repair torn ligaments and elbow injuries. Before we discoverd this phenemona of light, a torn ligament or an elbow injury was as devestating as a spinal cord injury. What phenemona am i talking about? a. chromatic aberration b. spherical aberration c. refraction d. total internal reflection e. none of the above 8. What is light? a. a wave b. a particle c. we don't know what it is 9. Why do planets revolve around the sun? a. gravity from the sun pulls them around itself b. the sun makes a "dent" in space, kind of like a baseball would make a "dent" in a flat blanket when the blanket is in the air, and the planets then revolve around the sun in the same way a coin follows the circular path of one of those cool yellow coin thingees. c. we don't know 10. True or false: EVERY magnet has a north pole and a south pole a. true b. false; although very rare, scientists have discovered magnets called "monopoles," where the magnet has either strictly one north pole or strictly one south pole c. we don't know enough about magnetism to say true or false. We don't know for sure if magnets really "do" have north and south poles, and therefore, we don't now if they have a "single" north or a "single" south pole. |
