Thomson observation
WebOct 19, 2024 · JJ Thomson's Experiment. Thomson then placed two magnets on either side of the plates to study the behavior of cathode rays in the presence of a magnetic field. His observation was that the presence of a magnetic field also deflected the cathode rays. The extent of deflection helped him determine the mass to charge ratio. WebThomson remarked that this might be due to the smallness of \(m\) or to the largeness of \(e\). He argued that \(m\) was small citing Lenard’s work on the range of cathode rays in air. The range, which is related to the mean free path for collisions, and which depends on the size of the object, was 0.5 cm.
