science chapter 15 Flashcards
pulse
single oscillation
a wave transfers energy without transferring
mass
a disturbance that transfers energy from one place to another without transferring mass
wave
when energy from something gives its energy to another thing
energy transfer
a wave that can only travel through solids, liquids, and gasses
mechanical wave
a material in which a wave travels
medium
a wave in which the disturbance is perpendicular to the direction the wave travels
transverse wave
the spot transverse waves are in before they are moving
rest position
the highest point on a transverse wave
crest
the lowest point on a transverse wave
trough
makes the particles in a medium move parallel to the direction that the wave travels
longitudinal wave
an example of a longitudinal wave is…
a springs coils moving closer together and farther apart in waves
the position in a longitudinal wave where the particles are closest together
compressions
the position in a longitudinal wave where the particles are farthest apart
rarefactions
an up & down/side to side movement of an object. sources of energy that produce mechanical waves
vibrations
