Average distance covered by α-particle in air before its ionizing power ceases is called its:
Correct answer: C. Range
- A. Trajectory
- B. Firing level
- C. Range
- D. Limit
Explanation
An α-particle travels a well defined distance in a medium before coming to rest. This distance is called the range of the particle. The range depends on the:ⅰ. charge, mass and energy of a particleⅱ. the density of the medium and ionization potential of the atoms of the medium
