Which type of radiation has very short (<10–3 nm) wavelengths, produced by nuclear explosions, lightning and less dramatic activity of radioactive decay?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Gamma.
The type of radiation characterized by very short wavelengths (less than 10–3 nm) is gamma radiation. Gamma rays are electromagnetic waves emitted during nuclear reactions, such as nuclear explosions, radioactive decay, and certain types of lightning. They have extremely high energy and can penetrate materials more effectively than other types of radiation, like alpha and beta particles. Gamma radiation is often associated with dangerous levels of radiation exposure, making it significant in fields like nuclear medicine and radiation safety.
