Why cathode ray tube experiment is not conducted at atmospheric pressure?

Text Solution

Verified by Experts

The correct Answer is:
At atmospheric pressure in the cathode tube the generated cathode rays shall face numerous collisions Hence the distance traveled by the rays will be infinitisimally small.
