ANS: A
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.

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.

| a. | An oral examination with dental images 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. |
| d. | Many dental diseases are typically discovered only through the use of dental images. |
ANS: D
An oral examination without dental images limits the practitioner to what is seen clinically. Many dental diseases and conditions produce no clinical signs and symptoms. Dental images are a necessary component of comprehensive patient care. Many dental diseases are typically discovered only through the use of dental images.

| 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.
