Which of the following radiations possesses maximum velocity and penetration power?
Correct answer: C. C
- A. A
- B. B
- C. C
- D. D
Explanation
Gamma (γ) rays are a form of electromagnetic radiation, meaning they are pure energy and travel at the speed of light, which is the maximum possible velocity. They also possess the highest penetrating power among common types of radiation (alpha, beta, and gamma) because they have no charge or mass and interact less with matter.

About Radioactive Decay
Radioactive decay is the spontaneous transformation of unstable nuclei, described by decay constant, activity, half life and the exponential decay law. Work includes alpha, beta and gamma emissions, decay equations and remaining nuclei, with half life distinguished from the time required for complete decay.
