Harmonic

Harmonics are sounds that are made up of different pitches or frequencies that sound good together. Imagine playing a guitar string and plucking it. The sound you hear is the first harmonic or the first sound wave. When you pluck the string, it vibrates back and forth, and this vibration creates sound.

However, depending on how hard you pluck or where you press your finger on the string, you can create different sounds, or harmonics. The second harmonic will be twice the frequency of the first; the third harmonic will be three times the frequency of the first, and so on. For example, if the frequency of the first harmonic is 100 Hz, the second harmonic will be 200 Hz, and the third harmonic will be 300 Hz.

Harmonics can also be found in music. When you listen to a song, you can hear different sounds or notes that blend together to make one bigger sound. These notes are at different frequencies, and they sound good together because they are harmonics. It's like playing with different colored Legos to make a bigger structure.

In summary, harmonics are sounds made up of different vibrations or frequencies that sound good together. They can be found in musical instruments, music, and even in everyday sounds we hear.
