ANSWER: B n
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 the
n n n n n n n n n n n n n n
negative electrode of a vacuum tube traveled in straight lines, produced heat, and resultedin a
n n n n n n n n n n n n n n n n

ANSWER: C n
Patient exposure is reduced with digital imaging. Digital sensors are more sensitive to x-rays than
