Which radiation passes through black body

Explanation

A black body is an idealized physical object that absorbs all radiation that falls on it. This means that it does not reflect or transmit any radiation, effectively making it impossible for any radiation to pass through it. In contrast, alpha particles are large and positively charged, thus unable to penetrate even small barriers; beta particles, being smaller and negatively charged, can penetrate more than alpha particles but still cannot pass through a black body; gamma radiation, while highly penetrating, will not pass through a black body due to its defining characteristic of complete absorption. Therefore, the correct answer is that no radiation can pass through a black body.
