Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the historical precursor?Nikola Tesla's 1898 demonstration of a radio-controlled boat
2. What is the contemporary significance?Critical role in industrial safety, scientific research, public safety, and military operations
3. What is radio control and how does it let us move machines from far away?Radio control uses invisible radio waves to send commands from a remote transmitter to a receiver in the machine. The receiver turns those signals into electrical commands that move motors or servos.
4. How did Nikola Tesla show that radio control could work?In 1898 Tesla used radio waves to steer a small boat, proving that machines could be guided without wires.

Radio Frequency (RF) Waves: Electromagnetic waves used for wireless communication, varying in frequency and wavelength.
Modulation: The process of encoding information onto a carrier wave for transmission.
Demodulation: The process of extracting information from a received modulated carrier wave.
Proportional Control: A control system where the output is proportional to the input signal, allowing for nuanced adjustments.
