observed this effect in a previous experiment (View Factors. You have also observed a similar effect in your life. The farther you move away from a friend, the harder it is to hear them. Or the farther you move away from a light source, the harder it is to see. Basically, nature provides many examples (including light, sound, and radiation) that follow an inverse square law. What an inverse square law says is that as you double the distance between source and detector, intensity goes down by a factor of four. If you triple the distance, intensity would decrease by a factor of nine. If you quadruple the distance, the intensity would decrease by a factor of 16, and so on and so on. As a result, if you move to a distance d away from the window of the GM counter, then the intensity of radiation decreases by a factor 1/r^2. Does your data follow a best fit line If not, why. Would the result be the same if you used an alpha emitting source How would your results change with a gamma emitter

Solution

Part 1

Radiations travel through electromagnetic waves. so in vaccum they have same counts as in a medium. so if we perform this experiment in vaccum then same effect is observed and intensity decreases as we move away from the source.

Part 2

Yes in vaccum inverse square law is verified as intensity is energy per unit area per unit time. as we move a distance d away from the source intensity decrease proportionaly to 1/d^2.as area is proportional to d^2. so in this case inverse square law is verified.
