Cathode Rays: A Journey from Discovery to Modern Physics

What are the rays that travel from cathode to anode in a discharge tube called?

The rays, traveling from cathode to anode in the discharge tube, are called__________.

The rays that travel from cathode to anode in a discharge tube are called "cathode rays."

Cathode rays are composed of a stream of electrons that are emitted by the cathode (negative electrode) and accelerated towards the anode (positive electrode) by an electric field. These rays were first discovered and studied in the late 19th century by scientists such as J.J. Thomson.

Through their experiments with vacuum tubes, Thomson and other scientists were able to investigate the properties of cathode rays. They discovered that cathode rays have a negative charge and can be deflected by magnetic and electric fields. This discovery played a critical role in the development of modern physics and electronics.

Overall, the study of cathode rays led to significant advancements in our understanding of atomic and subatomic particles. It paved the way for the development of technologies such as cathode ray tubes, which were used in early televisions and computer monitors. The legacy of cathode rays continues to influence scientific research and technological innovation today.
