Question 1 Report
Which of the following particles of ray has the highest penetrating power?
Answer Details
The correct option is "Gamma particles". Gamma particles are a type of electromagnetic radiation with the highest frequency and shortest wavelength. Due to their high energy and lack of charge, they can penetrate through materials with the highest density and thickness, such as concrete and lead. Beta particles are fast-moving electrons that can penetrate through thin metal sheets and cause damage to living cells. Alpha particles are helium nuclei and have the largest mass but low penetrating power, being stopped by a sheet of paper or a few centimeters of air. Electrons are negatively charged subatomic particles with moderate penetrating power, and neutrons have no charge and moderate penetrating power, being able to penetrate through materials with low density.
