Concept

Problem: Thomson observed that the cathode rays produced in the cathode-ray tube behaved identically, regardless of the particular metal used as cathode. (a) What is the significance of this observation?

FREE Expert Solution

Thomson observed that the cathode rays produced in the cathode-ray tube behaved identically, regardless of the particular metal used as cathode.

• cathode rays → deflected by electric electric or magnetic fields in a way consistent with being a streams of negative charge

• cathode rays → same regardless of the identity of the cathode material (metal)
