P And S More Flashcards
What are the differences between transverse and longitudinal waves?
Transverse waves oscillate perpendicular to the direction of energy transfer, while longitudinal waves oscillate parallel.
What evidence suggests that when waves are moving, it’s the wave that moves and not the medium?
The observation of stationary particles in a medium while waves pass through provides evidence.
How do scientists define compressions and rarefactions in a longitudinal wave?
Compressions are regions of high pressure and density, while rarefactions are regions of low pressure and density.
How do transverse waves transfer energy?
transfer energy through the oscillation of particles perpendicular to the direction of wave propagation.
longitudinal waves transfer energy?
transfer energy through the compression and rarefaction of particles in the direction of wave propagation.
Why do all longitudinal waves require a medium to travel in, but not all transverse waves?
Because require a medium because they rely on the compression and rarefaction
What is the key difference between the oscillations of transverse waves and longitudinal waves?
The key difference is that transverse waves oscillate perpendicular to the direction of wave propagation.
What are some of the different types of waves that fall under the categories of transverse and longitudinal waves?
Some types of transverse waves include electromagnetic waves, while longitudinal waves include sound waves.
Secondary waves
travels, only trough solids
secondary waves
Slower than p waves
Why do P waves have sound?
Travels through medium
-causes particles to move in the same direction as waves
• Vibrations creates compressions and rafefractions
-detected as sound by ears
Difference between p and s
waves
-P is primary waves
-travels through solids, liquids and gases
-Fastest seismic waves
-compressional waves
Longitudinal wave
A wave in which the vibration of the medium is parallel to the direction the wave travels
Transverse waves
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.
