Heinrich Geissler built the first vacuum tube in 1838. Wilhelm Roentgen
yu yu yu yu yu yu yu yu yu yu
discovered the x-ray on November 8, 1895. Johann Hittorf observed in 1870 that
yu yu yu yu yu yu yu yu yu yu yu yu yu
discharges emitted from the negative electrode of a vacuum tube traveled in
yu yu yu yu yu yu yu yu yu yu yu yu
straight lines, produced heat,
yu yu yu yu
and resulted in a greenish fluorescence. William Crookes discovered in the late
yu yu yu yu yu yu yu yu yu yu yu
1870s that cathode rays were streams of charged particles.
