Cathode rays are produced in the discharge tube when a voltage of about .... volts is applied and the pressure of the gas inside is of the order of....atm

Text Solution

AI Generated Solution

To solve the question regarding the production of cathode rays in a discharge tube, we can break it down into two parts: the voltage required and the pressure of the gas inside the tube. ### Step-by-Step Solution: 1. **Identify the Voltage Required:** - Cathode rays are produced when a high voltage is applied across the electrodes in a discharge tube. - The typical voltage required to generate cathode rays is approximately **10,000 volts**. ...
