Photoelectric Effects and deBroglie Equation: Practice Problem & Solution

84. In a discharge tube at $0.02 mm$, there is formation of (1996)
Crooke's dark space
Faraday's dark space
Both space partly
None of these.

Solution Explained:

To solve this problem, we apply the core principles of Photoelectric Effects and deBroglie Equation. Understanding the underlying formula is key to arriving at the correct answer below:

At a very low pressure of about $0.02 mm$ of Hg in a discharge tube, the Crookes dark space expands to fill the entire tube.
