Where can you watch cosmic quantum ray?

Answer 1

Not unlike wind, the human eye can't see cosmic rays directly, but their effects can be made quite visible, using various techniques. In cloud or bubble chambers, the cosmic ray collides with sufficient energy to leave a visible trail, albeit somewhat briefly, but the path of the cosmic ray becomes easily apparent. In spark chambers a technique using charged plates can cause sparks to jump between plates when the path of a cosmic ray creates an ionization channel along its path. Other techniques involve materials which will generate light when a cosmic ray strikes its surface, which can trigger electronics to amplify or make audible.

The word 'quantum' may be somewhat redundant in this context; remembering that a cosmic ray is actually made of of particles, be they protons or atomic nuclei traveling at high speed - they are really matter and not electromagnetic radiation as the name might suggest. Since matter does exist in discrete physical units or quanta, loosely one might say that all matter is quantized.
