3A.2 Wave Types Flashcards
what are transverse waves
a wave in which the oscillations occur perpendicular to the direction of movement of the wave energy
what are longitudinal waves
a wave in which the oscillations are parallel to the direction of movement of energy
what is the movement in transverse waves like
up and down, or left to right
how can transverse wave movement be illustrated
a student moves a robe up and down cause the particles to vibrate, pulling their neighboring particles up and down with them at which they pull there neighbouring particles up and down causing them to vibrate and they do that through their intermolecular forces
what is compersion
an area in a longitudinal wave in which the oscillations of the particles would put them closer to each other than their equilibrium state
what are rarefactions
an area in a longitudinal wave in which the oscillations of the particles would put them further apart than each other compared to their equilibrium state
how is sound in the air continue moving
because of the high-pressure areas and low-pressure areas in the air
how does compression of sound particles occur in air
it occurs when particles on either side of the high pressure and displaced towards it this means that the particles are being displaced against each other causing them to squash together
which type of seismic waves travel faster
primary waves
what type are primary seismic waves
longitudinal
what type are secondary seismic waves
transverse
