Q:

What is a medium of a wave?

A:

The medium of a wave is any substance that carries the wave, or through which the wave travels. Ocean waves are carried by water, sound waves are carried by air, and the seismic waves of an earthquake are carried by rock and soil.

Full Answer

A wave is a disturbance travelling through matter or space, transferring energy from one place to another. Mechanical waves, such a sound waves and water waves, carry energy through a medium, but the molecules of medium itself are generally not permanently displaced. Electromagnetic radiation, which includes light and radio waves, sometimes behaves as waves and sometimes as particles called photons. Electromagnetic waves can travel without a medium.

  • Q:

    What is the matter through which a wave travels called?

    A:

    Waves can travel through matter called a medium. This is true for mechanical waves that include sound, water and slinky waves. However, this is not the case for electromagnetic waves, which can travel through a vacuum.

  • Q:

    What type of wave does not require a medium?

    A:

    Electromagnetic waves do not require a medium to be transmitted. These waves, which freely travel through different types of materials, are produced due to the combined effects of a magnetic field and an electric field.

  • Q:

    What does the speed of a sound wave depend on?

    A:

    The speed of a sound wave depends on what type of medium it is traveling through, and if that medium is a gas or liquid, a significant change in temperature can also affect its speed. In air, the speed at which sound travels is about 1 mile every 5 seconds at 32 degrees Fahrenheit, but the speed of a sound wave traveling through solid rock is about 18 miles every 5 seconds. Sound travels faster through a solid substance like rock because, unlike liquids or gases, the molecules in a solid are held close together.

    What is a P-wave?

    A:

    A P-wave is a type of seismic wave that can travel through a continuum. A P-wave can also be referred to as a compressional wave, a primary wave or a pressure wave.
