Q:

What are the three aspects of sound waves?

A:

Quick Answer

The three aspects of sound waves are wavelength, frequency and amplitude. Wavelength describes the distance between each sound wave, and frequency relates to the number of waves counted in a specified amount of time. The energy in a sound wave is called amplitude.

Full Answer

The three aspects can also be seen when looking at a model of sound waves. Each sound wave has a peak and a trough, and wavelengths are the spaces measured between either the troughs or the peaks. Higher frequencies have shorter distances between the troughs or peaks. The amplitude of a sound is shown by the height of the sound wave, with higher waves tending to represent louder sounds. The more waves that occur in a period, the higher the pitch of the sound.

  • Q:

    How are sound waves produced?

    A:

    Sound waves occur when an object vibrates and transfers that energy into the air or another medium. When a vibrating object moves forward, it compresses the air molecules in front of it, and when it moves backward, it leaves a gap where they can expand or rarefy. The vibration produces many of these compression and rarefaction pairs, which travel away from the source of the vibration through the air.

  • Q:

    What are examples of sound waves?

    A:

    Music, speech and explosions are all examples of sound waves. Sound waves are mechanical vibrations in a compressible medium. The larger the amplitude of the waves, the louder the wave sounds. Because mechanical vibrations require a medium to vibrate, sound does not manifest in vacuums, such as space.

  • Q:

    What do sound waves look like?

    A:

    Sound waves are longitudinal waves of sound formed as it occurs. They cannot be seen with the naked eye, but they can be represented on a graph. There, sound waves are displayed as a series of vertical lines.

  • Q:

    How do sound waves transfer energy?

    A:

    Sound waves transfer energy by causing successive compressions and rarefactions in the particles of the medium without transporting the medium particles themselves. Sound in solids can also manifest as transverse waves, causing crests and troughs in the propagation medium.
