A phonograph is used for ________.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → producing sound
The phonograph, invented by Thomas Alva Edison in 1877, was the first machine that could record sound and play it back. A needle cut the sound vibrations as a groove on a rotating cylinder; running the needle along the groove again reproduced the sound. It was the forerunner of the gramophone and the record player.
