For which discovery did Henri Becquerel receive the Nobel Prize in Physics in 1903?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Spontaneous Radioactivity.
Henri Becquerel received the Nobel Prize in Physics in 1903 for his discovery of spontaneous radioactivity. This groundbreaking work involved the observation that certain materials, particularly uranium salts, emitted radiation without any external influence. Becquerel's experiments revealed that this radiation could expose photographic plates, indicating the presence of an unknown form of energy. His findings laid the foundation for future research in nuclear physics and chemistry, significantly advancing the understanding of atomic structure. Becquerel shared the Nobel Prize with Marie Curie and Pierre Curie, who further explored radioactivity, contributing to the field's development and its applications in science and medicine.
