waves Flashcards
1
Q
wave
A
a disturbance that transfers energy from one place to another and is made up of periodic motion
2
Q
transverse wave
A
wave whose motion is perpendicular to the direction of vibration of particles
3
Q
longitudinal wave
A
wave whose motion is parallel to the direction of vibration of particles
4
Q
crest
A
highest point of a transverse wave
5
Q
trough
A
lowest point of a transverse wave
6
Q
amplitude
A
maximum displacement of a point on a wave from its rest position
7
Q
wavelength
A
the shortest distance between any two points in phase
8
Q
period
A
time taken to produce one complete wave
9
Q
frequency
A
number of complete waves produced per second
10
Q
wave speed
A
average distance travelled by a wave per second
11
Q
wavefront
A
an imaginary line that joins all adjacent points on a wave that are in phase
