Waves
lowest point of a wave
What is a trough?
the distance between one point on a wave and a similar point (crest to crest; trough to trough, etc.)
What is a wavelength?
highest point of a wave
What is a crest?
repeating movement or disturbance that transfer energy through matter or space
What is a wave?
waves carry this from one location to another
What is energy?
spring system comes to a stop
What is due to friction in the system?
bending of a wave caused by a change in its speed as it moves from one medium to another
What is refraction?
only travels through a medium
What is a mechanical wave?
longitudinal waves that have dense regions and less dense regions
What are compressional waves?
two or more waves overlap and combine
What is interference?
What is matter?
less dense coils in a compressional wave
What is rarefaction?
the pitch of a vehicle approaching
What is higher?
causes greater amplitude
What is resonance?
cannot travel through a vacuum or space
What is a mechanical wave?
a restoring force that is proportional to its displacement
What is simple harmonic motion?
the measure of energy in a wave
What is amplitude?
can travel down a string
What is a transverse wave?
waves changes direction and bends toward it
What is diffraction?
perceived frequency of a sound wave determines its pitch
What is the Doppler effect?
the angle of incidence of a wave is always equal to the angle of reflection
What is the Law of Reflection?
intentionally decreases the amplitude of the oscillations
What is damping oscillation?
one cycle
What is a period?
the crest of one wave coincides with the trough of another wave
What is destructive interference occuring?
when a spring is stretched to its greatest displacement
What is maximum potential energy on a spring system?
