ANSWER: B t
Heinrich Geissler built the first vacuum tube in 1838. Wilhelm Roentgen discovered the x-

ray on November 8, 1895. Johann Hittorf observed in 1870 that discharges emitted from
t t t t t t t t t t t t t
the negative electrode of a vacuum tube traveled in straight lines, produced heat, and resulted in
t t t t t t t t t t t t t t t
a greenish fluorescence. William Crookes discovered in the late 1870s that cathode rays were
