ANS: B
An x-ray is a beam of energy that has the power to penetrate substances and record image
shadows on a receptor. A radiograph is a picture on film produced by the passage of x- rays
through an object or body. Radiography is the art and science of making dental images by the
exposure of a receptor to x-rays. Radiation is a form of energy carried by waves or streams of
particles.

limits the practitioner to what is seen clinically.
b. All dental diseases and conditions produce
clinical signs and symptoms.
c. Dental images are not a necessary
component of comprehensive patient care.

4. The x-ray was discovered by
a. Heinrich Geissler
b. Wilhelm Roentgen
c. Johann Hittorf
d. William Crookes
ANS: B
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 negative
electrode of a vacuum tube traveled in straight lines, produced heat,
and resulted in a greenish fluorescence. William Crookes discovered in the late 1870s that
cathode rays were streams of charged particles.
