24 Questions
What is the direction of particle displacement in a longitudinal wave?
Parallel to the direction of wave propagation
What occurs during a compression in a longitudinal wave?
The density and pressure of the medium increase
What is a rarefaction in a longitudinal wave?
A region where particles are furthest apart
What is the relationship between compressions and rarefactions in a longitudinal wave?
They are alternating regions of high and low pressure
What is an example of a longitudinal wave?
A slinky spring being pushed and pulled horizontally
What is the characteristic of particle movement in a longitudinal wave?
Particles move back and forth
What is the main difference between a compression and a rarefaction in a longitudinal wave?
The density of the medium
In a longitudinal wave, what happens to the pressure of the medium during a compression?
It increases above average
What is the result of the particles moving closer together in a longitudinal wave?
An increase in the medium's pressure
What is the characteristic of the medium's density during a rarefaction?
It is lower than average
How do compressions and rarefactions move through the medium in a longitudinal wave?
As alternating regions of high and low pressure
What is the visual representation of a longitudinal wave?
A slinky spring being pushed and pulled horizontally
What is the effect of a compression on the density of the medium in a longitudinal wave?
The density of the medium increases
In a longitudinal wave, what is the orientation of the particles' motion relative to the wave's propagation direction?
Parallel to the wave's propagation direction
During a rarefaction, what happens to the pressure of the medium?
The pressure of the medium decreases
What is the relationship between the density of the medium and its pressure during a compression?
The density increases, and the pressure increases
In a longitudinal wave, what is the pattern of compressions and rarefactions?
Alternating regions of high and low pressure, and high and low density
What is the characteristic of a longitudinal wave that distinguishes it from a transverse wave?
The particles of the medium move parallel to the wave's propagation direction
What is the primary reason why the density of the medium is higher during a compression?
The particles are closest together, resulting in a higher density.
Which of the following statements about compressions and rarefactions is true?
Compressions have a higher density and higher pressure, while rarefactions have a lower density and lower pressure.
What is the result of the alternating regions of high and low pressure in a longitudinal wave?
The compressions and rarefactions travel through the medium.
What is the relationship between the movement of the particles and the direction of the wave's propagation in a longitudinal wave?
The particles move parallel to the direction of the wave's propagation.
What is the characteristic of a longitudinal wave that distinguishes it from other types of waves?
The particles move parallel to the direction of the wave's propagation.
What is the visual representation of a longitudinal wave comparable to?
A slinky spring being pushed and pulled horizontally.
