In a discharge tube at 0.02 mm, there is formation of (a) Crooke's dark space (b) Faraday's dark space (c) both space partly (d) none of these

Answer: (a). As pressure falls to about 0.01 to 0.05 mm of Hg, the Crookes dark space grows and fills most of the tube. At 0.02 mm the Crookes dark space is formed. So the answer is (a) Crooke's dark space.

Cathode Rays, Thomson's Experiment & Gas Discharge

In a discharge tube at 0.02 mm, there is formation of

Show answer and solution

Answer: (a)

As pressure falls to about $0.01$ to $0.05\text{ mm}$ of Hg, the Crookes dark space grows and fills most of the tube.
At $0.02\text{ mm}$ the Crookes dark space is formed.
So the answer is (a) Crooke's dark space.
