Heinrich Rudolf Hertz (1857 - 1894) was a German physicist famous for his work in electromagnetism. He proved electric current has negligible mass through experiments. Hertz concluded Maxwell's electromagnetic theory of light was the most promising after comparing it to other theories. He devised an oscillator that transmitted and received electromagnetic waves, discovering radio waves. Hertz also conclusively proved Maxwell's theory by showing the energy from his oscillators traveled at the speed of light. His work laid the foundation for modern communications technology.

2. HEINRICH RUDOLF HERTZ (1857 – 1894)
•WAS A GERMAN PHYSICIST WHO IS MOST FAMOUS FOR HIS WORK IN THE
FIELD OF ELECTROMAGNETISM

3. #1 HE PROVED THAT ELECTRIC CURRENT
HAS NEGLIGIBLE MASS
•HERTZ DEMONSTRATED THROUGH A SERIES OF EXPERIMENTS THAT IF
ELECTRIC CURRENT HAS ANY MASS IT MUST BE INCREDIBLY SMALL

4. #2 HE COMPARED MAXWELL’S THEORY
WITH OTHER COMPETING THEORIES IN A
FAMOUS PAPER
•HE CONCLUDED THAT MAXWELL’S THEORY WAS THE MOST PROMISING.

5. #3 HEINRICH HERTZ DISCOVERED RADIO
WAVES
•HE DEVISED AN OSCILLATOR THAT FIRST CONTROLLED TRANSMISSION AND
RECEPTION OF ELECTROMAGNETIC WAVES
•HEINRICH HERTZ THUS DISCOVERED RADIO WAVES.

6. #4 HE CONCLUSIVELY PROVED MAXWELL’S
ELECTROMAGNETIC THEORY OF LIGHT
•HE SHOWED THAT THE ENERGY RADIATING FROM HIS ELECTRICAL
OSCILLATORS TRAVELED AT THE SPEED TO LIGHT, COULD BE REFLECTED,
REFRACTED, PRODUCED INTERFERENCE PATTERNS AND PRODUCED
STANDING WAVES.

7. #5 HERTZ LAID THE FOUNDATION FOR
MODERN COMMUNICATIONS TECHNOLOGY

8. #6 HE WAS THE FIRST TO DISCOVER
PHOTOELECTRIC EFFECT
•HE SHONE ULTRAVIOLET LIGHT ON ELECTRICALLY CHARGED METAL,
OBSERVING THAT UV LIGHT CAUSED THE METAL TO LOSE ITS CHARGE
FASTER THAN OTHERWISE.

10. #7 HE PRODUCED PIONEERING WORK IN
THE FIELD OF CONTACT MECHANICS
