Which scientist discovered the anode rays?

The scientist who discovered anode rays was Eugen Goldstein in 1886.

Anode rays are also known as canal rays. They were discovered while experimenting with discharge tubes. When high voltage was applied to a gas at low pressure, Goldstein observed rays moving in the opposite direction of cathode rays. These rays were positive in nature.

Key Points About Anode Rays

• Discoverer: Eugen Goldstein.
• Year: 1886.
• Nature: They are streams of positively charged ions.
• Importance: Their discovery led to the identification of protons later by Ernest Rutherford.

This discovery was important in the development of atomic structure as it helped scientists understand the presence of positive particles in atoms.
