When a radio signal was received by the cornier, the small metal pieces inside clean together and allow current to pass through. The current would trigger a bell or a piano attached to a paper strip, which would make a record of a signal. Why was the car here and important piece of technology?

a) It led to the development of other devices that use wave technology.
b) It allowed people to send images long distances.
c) It was the most advanced device that used wave technology ever produced.
d) It read directly to devices like computers.

Final answer:

The coherer led to the development of other devices that use wave technology, most notably influencing vacuum tube technology which was vital for advancements in electronics that are the basis of modern devices such as radios, televisions, and computers.

Step-by-step explanation:

The coherer was an important piece of technology because it led to the development of other devices that use wave technology. This early form of radio receiver used the coherer to detect radio waves and signal the receipt of a message, which in turn, would trigger connected devices like bells or pianos to create a record. The vacuum tube technology that succeeded the coherer, pioneered by individuals like Lee De Forest with the triode, was crucial for advancements in electronics, paving the way for modern devices such as computers, radios, and televisions.

Waves generated by a D.J. at a radio station are converted into electromagnetic waves, transmitted, and then received by radios, decoding the information back into sound waves. This illustrates the significant transformation in communication, leading from Marconi's transmission of Morse code to the broadcast of voice and music. The culmination of these technological advances had a profound impact on society, influencing wartime efforts such as codebreaking and computing, which fostered the development of early computers like the ENIAC.

Conclusively, the vacuum tube and subsequent innovations were crucial for electronic developments throughout the 1910s to 1960s, and further set the stage for the digital era, making the coherer an influential ancestor in the lineage of technological evolution.
