waves Flashcards
definition of a transverse wave
a transverse wave has a direction of vibration of particles that is perpendicular to the direction of wave travel.
definition of longitudinal wave
a longitudinal wave has a direction of vibration particles that is parallel to the direction of wave travel.
what is a crest?
a crest is the highest point of a transverse wave.
what is a trough?
a trough is the lowest point of a transverse wave.
what is an amplitude?
amplitude is the maximum displacement of a point from its rest position.
what is a wavelength?
a wavelength is the shortest distance between any two points of a wave which are in phase.
relationship between frequency and time.
f = 1/ T
definition of a period
a period is the time taken to produce a complete wave.
definition of frequency
frequency is the number of completed waves produced per unit time.
definition of wave speed
wave speed is the distance travelled by the wave per unit time.
what is the relationship between wave speed (v) and frequency (f) and wavelength (λ)
v = f λ
definition of wavefront
a wavefront is an imaginary line on a wave that joins all adjacent points that are in place.
