Q:

What has a higher frequency than the fundamental frequency?

A:

In acoustics, the harmonics of a sound all have a higher frequency than the fundamental frequency. The fundamental frequency is the lowest resonant frequency that a sound generator produces.

Harmonics are whole-number factors of the fundamental frequency. For example, the second harmonic has a frequency that is double that of the fundamental, while the third harmonic is triple the frequency.

Any object that vibrates at a regular frequency, such as a guitar string or the air in a brass instrument, generates a harmonic frequency structure.

Sound quality, or timbre, depends on the frequency and distribution of the harmonics, as well as the different media that give rise to these vibrations.

    What is the wavelength of the fundamental resonant frequency of a closed tube that is 35 cm long?

    A:

    The fundamental frequency of a closed tube that is 35 centimetres long is approximately 246.4 Hertz, assuming sound is traveling at 345 metres per second. The formula for obtaining this number is f(1)=nv/4L.

  • Q:

    What is sound frequency?

    A:

    The frequency of a sound is the rate at which wave crests reach a given point. Sound waves propagate outward from their source, as a series of compressions and rarefactions of the surrounding air. The peak of each cycle can be plotted as the crest of a wave, as can the low point or trough. The frequency with which these crests and troughs arrive gives sound its pitch.

    Why is sound important?

    A:

    Although there are many reasons sound is important; a couple reasons are that it allows humans and animals to hear and communicate, and it is a primary component in the functioning of sonar equipment. Sound occurs in a variety of waves, which have different characteristics and produce different types of noises.

    What is frequency reuse?

    A:

    Frequency reuse is the practice of splitting an area into smaller regions that do not overlap so that each utilizes the full range of frequencies without interference. The introduction of this concept was a major step in the development of mobile phone technology.
