In 1775, the Italian scientist, Alessandro Volta:
a. Invented the precursor to the wet-cell battery, a device that produced light
with static electricity.
b. Coined the terms vitreous and resinous to describe charged particles.
c. Used the term cathode ray to describe electrons emitted from the cathode
of an evacuated tube.
d. Used the terms positive and negative, rather than resinous and vitreous to
describe electrically charged particles.
In 1750, Benjamin Franklin conducted tests on:
a. Salts that could be deflected by a magnet, thereby, producing
b. Electromagnetic induction, studying the passage of electricity through
c. The production of fluorescent light.
Michael Faraday's contribution to pre-x-ray discoveries between 1831 and 1833
was that he:
a. Used the term cathode ray to describe electrons emitted from the cathode of
an evacuated tube.
b. Renamed the so-called vitreous and resinous charges.
c. Developed 2 basic laws of electrolysis and studied the passage of electricity
d. Recognized the medical applications of x-radiation.
