inverse square law. calibrated and was capable of giving sufficiently accurate results. perfect point source but it can be considered a point source at distances of about 10 times its dimensions. concluded that this health physics instrument gives very accurate results.
The Inverse-Square Law
The intensity of a star's light falls off with distance according to a simple mathematical law. We will test this law in the lab, and illustrate its key applications in astronomy.
In everyday life we describe light subjectively; for example, light is `good' if it enables us to do what we want to do, and `bad' if it doesn't. But light can be measured and described numerically. In particular, we can measure the intensity of light; if a given source produces one unit of light, two such sources will produce twice as much light, ten sources will produce ten times as much, and so on. Thus it makes sense to talk about the intensity of light in mathematical terms.
