The frequency of a note that is one octave higher than 500 Hz is 1000 Hz.

– In music and acoustics, an octave is an interval between two notes where the higher note has a frequency exactly double that of the lower note.
– Conversely, a note one octave lower than a given note has half its frequency.

This relationship between frequency and octave is fundamental to musical scales and harmony. For example, if A4 is tuned to 440 Hz, A5 (one octave higher) is 880 Hz, and A3 (one octave lower) is 220 Hz.
