Measuring Energy Lost in Each Slab
| By placing detectors between each metal slab, physicists measure the energy lost in each slab. The green bars indicate how much energy was lost in each slab. The energy is spread out over a number of layers depending how deep the shower goes. The green bars start out small, get quite tall, and then drop off. WARNING: If you do not have enough layers, you may miss some of the energy. How do they get the total energy? |  |
