NEET Physics Davisson-Germer Experiment MCQ Question
What was a significant finding of the Davisson-Germer experiment regarding the nature of cathode rays?
The charge to mass ratio (e/m) is independent of the material used.
Cathode rays are positively charged particles.
Cathode rays are emitted only from heated metals.
The speed of cathode rays is always greater than the speed of light.
Correct Answer
Detailed Explanation
The experiment demonstrated that the charge to mass ratio (e/m) of cathode ray particles is independent of the material used, suggesting their universality.
