Web27 jun. 2024 · JJ Thomson's cathode ray tube experiments. Thomson, a highly respected theoretical physics professor at Cambridge University, undertook a series of experiments designed to study the nature of electric discharge in a high-vacuum cathode-ray tube – he was attempting to solve a long-standing controversy regarding the nature of cathode … Web30 jul. 2024 · J.J. Thomson made a detailed study of the discharge of electricity through gases under very low pressure. This experiment was performed using a cathode ray tube (Crooke’s tube). It consists of a glass tube connected to two metal electrodes at two ends. There is a side tube connected to a vacuum pump to reduce pressure.

J. Thomson’s second experiment involving the deviation of an electron beam in a vacuum tube, called a Crookes Tube. A partial vacuum (less than 10-6 atm) is maintained in the tube. A high voltage (between 10 and 100 kV) is applied between two electrodes. The very intense electric field that results from this accelerates the few …

Therefore, we want to find ( ∂ T ∂ P) H, which is the Joule-Thomson coefficient, for which I shall be using the symbol µ. In the experiment we are discussing, we are interested in how temperature varies with pressure in ... WebHis 1897 experiment on cathode rays is generally regarded as the “discovery” of the electron. The purpose of J.J. Thomson’s experiments was clearly stated in the introduction to his 1897 paper. The experiments discussed in this paper were undertaken in the hope of gaining some information as to the nature of Cathode Rays.
