Intensity

Physics enjoyed an intense exam review, Honors Physics endured an intense exam (well, not that intense) and Physical Science investigated the inverse-square relationship associated with light intensity. Intensity of both sound and light decrease in proportion to 1/d², and your two graphs documented this relationship. The first graph (intensity vs. distance) demonstrated the rapid decrease in intensity with distance and the second graph (intensity vs. 1/distance² verfied the inverse-square relationship by producing a nice straight line that passed very close to the origin. We'll discuss the lab tomorrow and conclude our discussion of sound. Then, we turn our attention to light, its properties and behaviors. BTW, here's a good use for resonance:
