DUAL NATURE OF RADIATION AND MATTER Important Points: 1. J.J. T and Sir William Crookes studied the discharge of electricity through gases. At about 0.01 mm of Hg and at high voltage invisible streams called cathode rays are emitted. J.J. T called them streams of negative corpuscles. Johnston Stony suggested th Dual Nature of Radiation and Matter particles. They were found to travel with speeds ranging from about 0.1 to 0.2 times the speed of light (3 ×10 8 m/s). The presently accepted value of e/m is 1.76 × 1011 C/kg. Further, the value of e/m was found to be independent of the nature of the material/metal used as the cathod
