WebThe answer for intensity at the mower operator’s ears is larger than the intensity measured far away. That’s a good sign. The problem is much easier if you think in terms of ratios. Divide the two distances and you get the distance ratio- twenty in this case. Square the distance ratio to get the intensity ratio (four hundred). WebSection Summary. The energy carried by any wave is proportional to its amplitude squared. For electromagnetic waves, this means intensity can be expressed as Iave=c0E202 I ave = c 0 E 0 2 2 , where I ave is the average intensity in W/m 2, and E 0 is the maximum electric field strength of a continuous sinusoidal wave. how is gender a factor in sport and pe
