The
waves which travel along a spring when it is pushed and pulled at one end
are longitudinal wave. When a wave travels along the spring,then each turn of the spring moves back and forth by only a small distance in the direction of waves.
What is longitudinal wave short answer?
: a wave (such as a sound wave) in which the particles of the
medium vibrate
in the direction of the line of advance of the wave.
What do you mean by longitudinal wave?
Longitudinal wave, wave
consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave
. … Sound moving through air also compresses and rarefies the gas in the direction of travel of the sound wave as they vibrate back and forth.
What are longitudinal and transverse waves Class 9?
In a longitudinal wave,
the displacement of the particles happens parallel to the direction the wave travels
. … In contrast, the displacement of particles in the transverse wave is perpendicular to the direction the wave is travelling.
What is longitudinal wave and examples?
In longitudinal waves , the vibrations are parallel to the direction of wave travel. Examples of longitudinal waves include:
sound waves
.
ultrasound waves
.
seismic P-waves
.
What is another word for longitudinal wave?
Longitudinal waves, also known as “
l-waves”
, are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave.
What is another name for longitudinal wave?
Mechanical longitudinal waves are also called
compressional or compression waves
, because they produce compression and rarefaction when traveling through a medium, and pressure waves, because they produce increases and decreases in pressure.
What is transverse wave Class 9?
Transverse wave is
one in which individual particles of medium move about their mean position in a direction perpendicular to the direction of wave propagation
. … When a transverse wave travels horizontally in a medium,the particles of medium vibrate up and down in vertical direction.
Is sound is a longitudinal wave?
Sound waves in air and fluids are
longitudinal waves
, because the particles that transport the sound vibrate parallel to the direction of the sound wave’s travel.
What is a longitudinal wave Class 8?
Sound | Short/Long Answer Questions
Longitudinal waves are
waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of propagation of the wave
.
What are the major differences between longitudinal and transverse waves?
Transverse waves are always characterized by
particle motion being perpendicular to wave motion
. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
What is the difference between transverse waves and longitudinal?
The direction of these oscillations
is the difference between longitudinal or transverse waves. In longitudinal waves , the vibrations are parallel to the direction of wave travel. In transverse waves , the vibrations are at right angles to the direction of wave travel.
Do longitudinal waves need a medium?
Yes
, longitudinal waves need a medium to continue moving forward.
What are the 2 main parts of a longitudinal wave?
A
compression
is where the particles of the medium are closest together, and a rarefaction is where the particles are farthest apart. Amplitude is the distance from the relaxed point in the medium to the middle of a rarefaction or compression. A wavelength is the distance between two equivalent points.
Why is sound longitudinal wave?
Sound waves in air (and any fluid medium) are longitudinal waves
because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves
. … Other surrounding particles begin to move rightward and leftward, thus sending a wave to the right.
What are the different types of waves?
Types and features of waves
Waves come in two kinds,
longitudinal and transverse
. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
