Explanations: answer key for all 10 questions

Q1: Who predicted electromagnetic waves mathematically in the 1860s?
Answer: James Clerk Maxwell
His equations showed that light is an electromagnetic wave and that other such waves should exist.
Q2: Who first proved radio waves exist in experiments in the late 1880s?
Answer: Heinrich Hertz
The unit of frequency, the hertz, is named in his honor.
Q3: Who sent the first transatlantic radio signal in 1901?
Answer: Guglielmo Marconi
The Morse letter S traveled from Cornwall to Newfoundland.
Q4: In 1943, the US Supreme Court upheld key radio patents of whom?
Answer: Nikola Tesla
The decision overturned several of Marconi's patents, months after Tesla's death.
Q5: Who made what is often called the first radio voice and music broadcast in 1906?
Answer: Reginald Fessenden
He played the violin and read from the Bible on Christmas Eve.
Q6: Which device by Lee de Forest amplified radio signals?
Answer: Audion triode
It made long-distance radio and broadcasting practical.
Q7: Who invented FM radio in the 1930s?
Answer: Edwin Armstrong
FM reduced static compared with AM.
Q8: How did radio help during the Titanic disaster in 1912?
Answer: Operators called nearby ships for rescue
The Carpathia rescued about 700 survivors.
Q9: Which 1954 product was the first commercial transistor radio?
Answer: Regency TR-1
Sony's TR-55 followed in 1955.
Q10: Which 1938 radio drama caused confusion with a fake Martian invasion?
Answer: The War of the Worlds

Radio Inventions Quiz – Waves Through the Air

Radio began with theory. James Clerk Maxwell predicted electromagnetic waves, Heinrich Hertz proved they existed and inventors like Marconi, Tesla and others turned the discovery into wireless communication around 1900.

Early radio sent Morse code between ships and stations. Soon inventors found ways to transmit voices and music, and broadcasting stations appeared in the 1920s, bringing news, sports and entertainment into homes across the world.

Radio kept evolving with FM sound, transistor radios and satellite and internet streaming. It also led to technologies like radar, television, Wi-Fi and mobile phones, which all use radio waves to carry information.
