Question 1

Samuel F. B. Morse:&#10;A) Developed regenerative circuit to increase amplification&#10;B) First successful demonstration of wireless telegraph&#10;C) Invented the electromagnetic telegraph&#10;D) Invented the telephone

Accepted Answer

Samuel F. B. Morse is credited with inventing the electromagnetic telegraph, which revolutionized communication across long distances. This invention paved the way for future advancements in communication technology.

Question 2

Alexander Graham Bell&#10;A) Invented the electromagnetic telegraph&#10;B) Invented the telephone&#10;C) Invented alternating current&#10;D) Projected first radio wave

Accepted Answer

Alexander Graham Bell is credited with inventing the telephone in 1876.

Question 3

James Clerk Maxwell&#10;A) Predicted existence of radio waves&#10;B) First voice transmission&#10;C) Invented alternating current&#10;D) Projected first radio waves

Accepted Answer

James Clerk Maxwell's equations predicted the existence of radio waves in 1864, before their discovery by Heinrich Hertz in 1886. Maxwell's work on electromagnetism laid the foundation for the development of modern radio communication. He did not invent alternating current or project the first radio waves.

Question 4

Heinrich Hertz&#10;A) Developed first diode tube&#10;B) Projected first radio waves&#10;C) Predicted existence of radio waves&#10;D) First voice transmission

Accepted Answer

Heinrich Hertz is credited with proving the existence of radio waves through his experiments in the late 19th century, thereby projecting the first radio waves.

Question 5

Guglielmo Marconi&#10;A) Projected first radio waves&#10;B) Developed the Audion tube&#10;C) Develops regenerative circuit to increase amplification&#10;D) First successful demonstration of wireless telegraph

Accepted Answer

Guglielmo Marconi is credited with the first successful demonstration of wireless telegraphy (radio communication) in the late 19th century. He did not project the first radio waves, as they are a natural phenomenon, nor did he develop the Audion tube or the regenerative circuit, both of which were advancements in electronics that came after Marconi's initial discoveries.

Question 6

Nikola Tesla&#10;A) First successful demonstration of wireless telegraph&#10;B) Developed first diode tube&#10;C) Predicted existence of radio waves&#10;D) Invented alternating current

Accepted Answer

Nikola Tesla is best known for inventing the alternating current (AC) electrical system, which is still the predominant method of electrical power transmission today. While he did make important contributions to the development of wireless communication, such as predicting the existence of radio waves, his invention of the AC system had a far greater impact on the modern world. He also did not invent the diode tube, although he did work on early forms of vacuum tubes.

Question 7

John A. Fleming&#10;A) Developed first diode tube&#10;B) Reports on sinking of the Titanic&#10;C) Predicted existence of radio waves&#10;D) First voice transmission

Accepted Answer

John A. Fleming invented the first thermionic valve or diode tube, which was a major development in the field of electronics.

Question 8

Lee De Forest&#10;A) Projected first radio waves&#10;B) Developed the Audion tube&#10;C) Develops regenerative circuit to increase amplification&#10;D) First successful demonstration of wireless telegraph

Accepted Answer

Lee De Forest is credited with developing the Audion tube, which was a crucial advancement in the development of radio and electronic technology.

Question 9

Reginald Fessendon&#10;A) Developed first diode tube&#10;B) Reports on sinking of the Titanic&#10;C) Predicted existence of radio waves&#10;D) First voice transmission

Accepted Answer

Fessenden made a significant contribution to the field of radio by achieving the first transmission of speech by radio waves in 1900.

Question 10

Edwin Armstrong&#10;A) Develops regenerative circuit to increase amplification&#10;B) First successful demonstration of wireless telegraph&#10;C) Invented the electromagnetic telegraph&#10;D) First man on the moon

Accepted Answer

Edwin Armstrong is credited with developing the regenerative circuit in 1912, which greatly increased the amplification of radio signals. This invention was a significant advancement for radio communication technology.
