Question

Arrange $\alpha ,\beta$ and $\gamma$-rays in ascending order with respect to their penetrating power.

Answer 1

1. Penetrating power refers to how far a beam or particles travel before they lose their energy.
2. Charged particles interact with the substances and eventually lose their energy, means more the electric charge, less the penetrating power.
3. As $\gamma$-rays do not have any electric charge, their penetrating power is high and $\alpha ,\beta$-rays have electric charge, therefore they have low penetrating power.
4. Arranging them in ascending order with respect to their penetrating power, $\alpha <\beta <\gamma$.
