Q
  • Demonstrated a current of electricity by transmitting electricity from a ‘LEYDEN JAR’ through wires and a vacuum tube.
  • ‘Leyden Jar’ a simple device that ‘stores’ static electricity in large amounts. It was the original form of the ‘CAPACITOR’ ; Ben Franklin perform many electrical experiments using these devices.

Q

Produced the first known radiograph in the United States on January 2, 1986

A

MICHAEL IDVORSKY PUPIN

17
Q
  • Primary concerns was working with Fluoroscopy.
  • After he and his staff performed numerous experiments they did discovered the use of calcium tungstate.
  • One of Edison’s assistant, Claronce Madison Dally, suffered radiation damage as a result of his work.
A

THOMAS ALVA EDISON

18
Q
  • Noticed that radium killed diseased cells, which was the first suggestion of the medical utility of radioactivity.
  • 1880, Pierre and his older brother Jacques (1856-1941) demonstrated the piezoelectric effect.
A

PIERRE CURIE

19
Q

Induced an electric current by moving a magnetic in and out of a coil in 1891. From this experiment electromagnetic induction was discovered.

A

MICHEAL FARADAY

20
Q

Made the most significant improvement on induction coils.

A

HEINRICH DANIEL RUHMKORFF OF PARIS

21
Q

Conducted several experiments with cathode rays, streams of electrons emitted from the surface of a cathode.

A

JOHAN WILHELM HITTORF

22
Q

Furthered study the cathode rays and demonstrated that matter was emitted from the cathode with enough energy to rotate a wheel placed within a tube.

A

WILLIAM CROOKES

23
Q
  • Found that cathode rays could penetrate thin metal and would project a few centimeters into air.
  • Also studied the deflection of rays as a result of magnetic field.
  • Did tremendous amount of research with cathode rays determined their energies by measuring the amount of penetration.
A

PHILIPP LENARD

24
Q
  • Produced radiograph in 1890
  • His achievement was recognized only in retrospect and after the discovery of x-rays by Wilhelm Conrad Roentgen.
  • He wasn’t credited with the discovery of x-rays.
A

WILLIAM GOODSPEED

25
Q
  • Produced the first photograph copy of written material in 1727
A

JOHAN HEINRICH SCHOLTZ

26
Q
  • Produced a film with a gelatin silver bromide emulsion that has remained the basic component for film.
