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.
Which is an example of longitudinal wave?
A sound wave traveling through air is a classic example of a longitudinal wave. As a sound wave moves from the lips of a speaker to the ear of a listener, particles of air vibrate back and forth in the same direction and the opposite direction of energy transport.
What is longitudinal wave and transverse waves?
Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.
Are all sound waves longitudinal?
All electromagnetic waves (light waves, microwaves, X-rays, radio waves) are transverse. All sound waves are longitudinal.
What uses a longitudinal wave?
A sound wave is a significant example of a longitudinal wave. When a speaker speaks some words in front of the microphone, he/she hit the air thousands of time per second at different frequencies. The sound particles travel along with the air particles and enter the mic to produce sound.
What are longitudinal waves Class 9?
Longitudinal waves are the waves where the displacement of the medium is in the same direction as the direction of the travel of the wave.
What are transverse and longitudinal waves give an example of each?
In a transverse wave, the particles are displaced perpendicular to the direction the wave travels. Examples of transverse waves include vibrations on a string and ripples on the surface of water.An example of longitudinal waves is compressions moving along a slinky.
What is longitudinal and transverse wave Class 9?
In a longitudinal wave, the medium or the channel moves in the same direction with respect to the wave. Here, the movement of the particles is from left to right and force other particles to vibrate. In a transverse wave the medium or the channel moves perpendicular to the direction of the wave.
What are the features of a longitudinal wave?
Characteristics of Longitudinal Waves. As in the case of transverse waves the following properties can be defined for longitudinal waves: wavelength, amplitude, period, frequency and wave speed. However instead of peaks and troughs, longitudinal waves have compressions and rarefactions.
Can longitudinal waves be polarized explain?
Longitudinal waves cannot be polarized. The reason behind this is that the transverse waves can vibrate in all directions perpendicular to the direction of propagation.Note: Longitudinal waves cannot be polarized because their particles vibrate in the same direction that the wave travels.
What is longitudinal wave Class 7?
Solution : 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 is a wave sound?
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person’s vocal chords.
Is sound a transverse wave?
Sound waves are not transverse waves because their oscillations are parallel to the direction of the energy transport. Among the most common examples of transverse waves are ocean waves.
