shadows on a receptor.
c. a high-energy radiation produced by the
collision of a beam of electrons with a
metal target in an x-ray tube.
d. a branch of medicine that deals with the
use of x-rays.
CORRECT CHOICE:- A
RATIONALE :->>>Radiation is a form of energy carried by waves or streams of
particles. An x-ray is a beam of energy that has the power to penetrate substances and
record image shadows on a receptor. X-radiation is a high-energy radiation produced by
the collision of a beam of electrons with a metal target in an x-ray tube. Radiology is a
branch of medicine that deals with the use of x-rays.

2. A radiograph is defined as
a. a beam of energy that has the power to
penetrate substances and record image
shadows on a receptor.
b. a picture on film produced by the passage
of x-rays through an Object or body.
c. the art and science of making radiographs
by the exposure of an image receptor to x-
rays.
d. a form of energy carried by waves or a
stream of particles.
CORRECT CHOICE:- B
RATIONALE :->>>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.

b. All dental diseases and conditions produce
clinical signs and symptoms.
c. Dental images are not a necessary

a. Heinrich Geissler
b. Wilhelm Roentgen
c. Johann Hittorf
d. William Crookes
CORRECT CHOICE:- B
RATIONALE :->>>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.
