Three paths of radioactive are observed as shown in the figure in the presence of electric field. Which type of radiation is shown in path 1?
Correct answer: B. Gamma
- A. Alpha
- B. Gamma
- C. Beta
- D. Cathode rays
Explanation
Gamma rays are electromagnetic waves and are neutral. The presence of an electric field does not affect their path of motion and they continue travelling in a straight line. Whereas, alpha, beta and cathode rays are deflected by electric fields.

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.
