This stated that there was a dual nature to things -- an electron was a wave and a particle, for example -- … WebThe statement in the video is wrong. In 1897, J. J. Thomson used an electric field (V) to accelerate electrons into a magnetic field (B). The magnetic field deflected the electrons into circular paths of known radius (r). He could then calculate the charge-to-mass ratio (e/m) of the electron. e/m = 2V/ (B²r²)
