Final Answer:
In Physics the William Bragg and his son awarded the Nobel Prize in 1915. Therefore, the correct option is B) Physics.
Step-by-step explanation:
William Henry Bragg and his son, William Lawrence Bragg, jointly received the Nobel Prize in Physics in 1915. Their honored work revolved around their groundbreaking development of X-ray crystallography. This innovative technique allowed for the examination of crystal structures through the use of X-rays, marking a pivotal moment in the field of physics.
The Braggs' method enabled scientists to explore the arrangement of atoms within crystals, revealing the fundamental atomic and molecular structures of various materials. Their contribution laid the foundation for a deeper understanding of matter at the atomic level, unlocking new avenues for research in chemistry, biology, and material science.
Their accomplishment in X-ray crystallography was instrumental in advancing scientific knowledge and opened doors for subsequent discoveries, including the determination of molecular structures and the elucidation of complex biological molecules such as DNA. The Nobel Prize in Physics was awarded to them in recognition of their profound impact on the scientific community and their pioneering role in unraveling the mysteries of atomic structures through the innovative application of X-rays. Therefore, the correct option is B) Physics.
