6.1.1 Transverse and Longitudinal Waves

Cards (42)

Transverse waves are waves in which the displacement of particles is perpendicular
Longitudinal waves are waves in which the displacement of particles is parallel
Match the characteristic of a transverse wave with its description:
Particle Displacement ↔️ Perpendicular to energy transfer
Peaks and Troughs ↔️ Highest and lowest points of the wave
Wavelength ↔️ Distance between two successive peaks or troughs
Frequency ↔️ Wave cycles per second
Arrange the steps to describe the motion of particles in transverse and longitudinal waves:
1️⃣ Transverse waves: Particles move perpendicular to energy transfer
2️⃣ Longitudinal waves: Particles move parallel to energy transfer
3️⃣ Transverse waves: Peaks and troughs occur
4️⃣ Longitudinal waves: Compressions and rarefactions occur
In transverse waves, the particle displacement is perpendicular to the direction of energy transfer.
In longitudinal waves, the displacement of particles is parallel
The wavelength in a longitudinal wave is the distance between two successive compressions or rarefactions
Light waves are examples of transverse waves. 
True
Longitudinal waves cannot travel in a vacuum.
False
What are examples of transverse waves?
Light and water waves
Key characteristics of longitudinal waves include compressions and rarefactions
In longitudinal waves, particles move back and forth in the same direction as the wave is traveling
Define a longitudinal wave.
Parallel particle displacement
What is the direction of particle movement in a transverse wave?
Perpendicular
The particle displacement in a transverse wave is perpendicular to the direction of energy transfer
Match the characteristics of transverse waves with their descriptions:
Particle Displacement ↔️ Perpendicular to energy transfer
Peaks and Troughs ↔️ Highest and lowest points
Wavelength ↔️ Distance between peaks
Frequency ↔️ Cycles per second
What is the direction of particle movement in a longitudinal wave?
Parallel
What are the regions of low pressure in a longitudinal wave called?
Rarefactions
The frequency of a longitudinal wave measures the number of wave cycles per second.
True
Light and water waves are examples of transverse waves. 
True
Sound waves and seismic waves are examples of longitudinal waves.
True
In transverse waves, light waves travel forward while their electric and magnetic fields oscillate up and down
In longitudinal waves, particles oscillate back and forth in the same direction as the wave travels. 
True
Match the characteristic of a longitudinal wave with its description:
Particle Displacement ↔️ Parallel to energy transfer
Compression ↔️ Region of high pressure
Rarefaction ↔️ Region of low pressure
Compressions in longitudinal waves are regions of high pressure.
True
What is the frequency of a wave?
Cycles per second
What is the direction of particle displacement in transverse waves?
Perpendicular
In transverse waves, particles move up and down or side to side, while in longitudinal waves, they move back and forth
Sound waves are examples of transverse waves.
False
What is the direction of particle movement in a transverse wave relative to the direction of energy transfer?
Perpendicular
Compressions are regions of high pressure in longitudinal waves.
True
Longitudinal waves feature compressions, which are regions of high pressure
In transverse waves, particles move up and down or side to side as the energy travels forward. 
True
What is the wavelength of a transverse wave defined as?
Distance between peaks
The highest and lowest points of a transverse wave are called peaks and troughs
In longitudinal waves, particles move back and forth in the same direction as the wave. 
True
Sound waves are an example of a longitudinal wave
Match the characteristics of longitudinal waves with their descriptions:
Particle Displacement ↔️ Parallel to energy transfer
Compression and Rarefaction ↔️ Regions of high and low pressure
Wavelength ↔️ Distance between compressions
Frequency ↔️ Cycles per second
Both transverse and longitudinal waves transfer energy in the forward direction. 
True

Air ↔️ Sound waves
Fluid ↔️ Pressure waves
Solid ↔️ Compression waves in metals
