In the previous experiments you examined closely the directions from which cosmic rays come. In Activity 4 you will use a similar setup this information to calculate the speed at which cosmic rays travel.
In earlier experiments you observed that Cosmic Rays seem to be moving very fast. With this experiment you will actually calculate the speed of a Cosmic Ray.
What is the average speed of a Cosmic Ray?
