Here's a breakdown:

* Fundamental Frequency: This is the lowest frequency at which a string or an object can vibrate. It corresponds to the simplest standing wave pattern, with one complete wave between the ends of the string or object.

* Overtones: These are frequencies that are higher than the fundamental frequency and are whole-number multiples of it. Each overtone corresponds to a more complex standing wave pattern, with additional nodes and antinodes along the string or object.

Standing Waves:

Standing waves are created when two waves of the same frequency traveling in opposite directions interfere with each other. This interference results in points of zero displacement called nodes and points of maximum displacement called antinodes. These points remain fixed in space, creating the illusion of a stationary wave.

In Summary:

Both the fundamental frequency and overtones create standing waves, which are characteristic patterns of vibration with fixed nodes and antinodes. The complexity of the standing wave pattern increases with each overtone, as the frequency increases.
