Which is a longitudinal wave that requires a medium to move?
An example of a longitudinal wave that requires a medium to move is sound. Sound is a mechanical wave, which means it needs a medium to propagate. …
What does a longitudinal wave require?
Longitudinal waves are waves in which the vibration of the medium is parallel to the direction the wave travels and displacement of the medium is in the same (or opposite) direction of the wave propagation.
What waves do not require a medium?
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Do longitudinal waves have amplitude?
In a longitudinal wave, particles of the medium move back and forth in the same direction as the wave. Wave amplitude of a longitudinal wave is the distance between particles of the medium where it is compressed by the wave. The closer together the particles are, the greater the amplitude of the wave.
What types of waves require a medium to travel?
Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.
What is the frequency of a longitudinal wave?
Period and Frequency The time taken by the wave to move one wavelength is known as the period. The frequency of the longitudinal wave is the number of wavelengths per second.
What kind of medium does a longitudinal wave need?
Longitudinal wave (like sound waves) required a material medium (e.g. air) for their transmission hence cannot pass through the vacuum.
Which is produced perpendicular to a transverse wave?
A longitudinal wave (sound) is always produced perpendicular to a transverse wave (light), and light does not require a medium in order to propagate, so why do so many people say that sound requires a medium to propagate? This wave of squished and stretched spacetime is a longitudinal wave just like sound.
Do you need a medium for mechanical waves?
Electromagnetic waves do not require a medium in order to transport their energy. Mechanical waves are waves that require a medium in order to transport their energy from one location to another. Sound is a mechanical wave and cannot travel through a vacuum. Click to see full answer.
Why do transverse waves need a medium to propogate?
Mechanical transverse waves require a material medium and propogate by means of vibrations of the medium perpendicular to the direction of travel. Electromagnetic (EM) waves (such as light) are also transverse waves but they do not require a medium and thus can pass through a vacuum (see intro). why do longitudinal waves need a medium?
