The fact that both the violin and the flute notes travel through the same medium, air, at the same speed ensures that they arrive at our ears simultaneously, regardless of their differences in sound characteristics.

The different sounds produced by a violin and a flute, despite traveling through the same medium, are due to variations in their frequency content, amplitude, and harmonic structure, which affect their perceived characteristics such as pitch, timbre, and intensity.

Pitch is one of the characteristics of sound, and it refers to the perceived frequency of a sound wave. The pitch of a violin note may differ from that of a flute note even if they arrive at our ears ...

The time period of a sound wave is represented by the symbol T, and its SI unit is second (s).

The time taken by two consecutive compressions or rarefactions to cross a fixed point is called the time period of the wave. It represents the duration of one complete oscillation of the sound wave.

Hertz (Hz) is the unit used to measure frequency and it represents the number of oscillations or cycles per second. For example, a frequency of 100 Hz means that there are 100 oscillations occurring per second.

Frequency is typically represented by the Greek letter ν (nu) and its SI unit is hertz (Hz).

One complete oscillation in terms of sound wave frequency is the change in density from the maximum value to the minimum value, and then back to the maximum value again.

Frequency can be likened to the number of times a drum is beaten in a given time period. If you beat a drum ten times in one minute, the frequency of your drumming is ten beats per minute.

Frequency in the context of sound waves refers to the number of compressions or rarefactions that pass a point in the medium per unit time.
