Who? How? What? - The record

The record is a medium that allows sound waves to be recorded and played back. It has historically been used as the dominant medium for recording and playing music and continues to hold great cultural value today.

From a scientific point of view, the record is an interesting object because it has both acoustic and physical properties. When recording, the sound is recorded onto a rotating record using a microphone. The sound waves are engraved into a spiral-shaped groove, which is then stored on the record.

The record is an analog medium because it records and plays back sound waves directly. This is in contrast to digital media such as CDs or MP3s, which convert and store the sound waves into digital information. This analog recording process gives the record a special sound quality that many music lovers appreciate.

The physics of the record is also interesting as it requires complex rotation and oscillations. The record rotates at a certain speed, which is determined by the frequency of the sound waves. The groove on the record also has a certain width and depth, which can affect the sound quality.

The record also has its limitations. For one thing, it has a limited lifespan because the shellac or vinyl materials can age and wear out over time. On the other hand, the record is susceptible to dust, scratches and other damage that can affect the sound quality.

Overall, the record is an interesting object from a scientific point of view that can teach us a lot about the physics of sound and the recording of music.
