Sir William Crookes

Sir William Crookes was a British scientist known for his pioneering work in chemistry and physics in the late 19th century. He is best recognized for inventing the Crookes tube, an early type of vacuum tube that led to the discovery of cathode rays, a key component in the development of television and radiation research. Crookes also studied the properties of matter and conducted experiments on the elements, contributing to the periodic table. His work laid the foundation for modern physics and has had lasting impacts in various scientific fields, including the study of electromagnetic radiation.
