false, they vibrate parallel
transverse
Disturbance in particle motion parallel to the wave velocity is called a longitudinal wave. Disturbance in particle motion perpendicular to the wave velocity is called a transverse wave.
Motion Perpendicular to the ground is called horizontal motion.
a transverse wave
A sound wave, like any other wave, is introduced into a medium by a vibrating object. The vibrating object is the source of the disturbance that moves through the medium. The vibrating object that creates the disturbance could be the vocal cords of a person, the vibrating string and sound board of a guitar or violin, the vibrating tines of a tuning fork, or the vibrating diaphragm of a radio speaker. Regardless of what vibrating object is creating the sound wave, the particles of the medium through which the sound moves is vibrating in a back and forth motion at a given frequency. The frequency of a wave refers to how often the particles of the medium vibrate when a wave passes through the medium. The frequency of a wave is measured as the number of complete back-and-forth vibrations of a particle of the medium per unit of time. If a particle of air undergoes 1000 longitudinal vibrations in 2 seconds, then the frequency of the wave would be 500 vibrations per second. A commonly used unit for frequency is the Hertz (abbreviated Hz), where 1 Hertz = 1 vibration/second As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. This is sensible since each particle vibrates due to the motion of its nearest neighbor. The first particle of the medium begins vibrating, at say 500 Hz, and begins to set the second particle into vibrational motion at the same frequency of 500 Hz. The second particle begins vibrating at 500 Hz and thus sets the third particle of the medium into vibrational motion at 500 Hz. The process continues throughout the medium; each particle vibrates at the same frequency. And of course the frequency at which each particle vibrates is the same as the frequency of the original source of the sound wave. Subsequently, a guitar string vibrating at 500 Hz will set the air particles in the room vibrating at the same frequency of 500 Hz, which carries a sound signal to the ear of a listener, which is detected as a 500 Hz sound wave.
resistance to motion is called inertia
Transverse wave.
transverse
Disturbance in particle motion parallel to the wave velocity is called a longitudinal wave. Disturbance in particle motion perpendicular to the wave velocity is called a transverse wave.
Both parallel and perpendicular to the motion of the wave at the same time/Perpendicular to the motion of the wave/Parallel to the motion of the wave - APEXPerpendicular to the motion of the wave.Parallel to the motion of the wave.Both parallel and pependicular to the motion of the wave at the same time.
The molecules vibrate perpendicular to the direction of propagation or motion.
transverse waves
Transverse waves occur when the motion of medium is at right angels (perpendicular) to the direction of the wave
Motion Perpendicular to the ground is called horizontal motion.
Vertical motion is the motion that is perpendicular to the ground.
A wave in a body of water is a traveling transverse wave because the motion of the medium (water) is perpendicular to the motion of the wave.
Longitudinal wave
Any kind of disturbance triggers mechanical waves that propagate perpendicular to the motion of disturbance. However for mechanical motion, it is necessary that the wave is propagated in a medium.
