a wave that travels from 1 place to another
progressive wave
1 of 18
a wave where the oscillations are parallel to the direction of wave propagation e.g. sound
longitudinal wave
2 of 18
a wave where the oscillations are perpendicular to the direction of wave propagation
transverse wave
3 of 18
the distance traveled in a particular direction
displacement
4 of 18
the maximum displacement of a wave from its mean position
amplitude
5 of 18
the smallest distance between 1 point on a wave and the identical point on the next wave
wavelength
6 of 18
the time taken for one complete pattern of oscillation
period
7 of 18
the number of oscillations per unit time
frequency
8 of 18
when waves rebound from a barrier, changing direction but remaining in the same medium
reflection
9 of 18
when waves change direction when they travel from 1 medium to another due to a difference in the wave speed in each medium
refraction
10 of 18
when a wave spreads out after passing around an obstacle or through a gap
diffraction
11 of 18
a transverse wave oscillating only in one plane
Plane polarised waves
12 of 18
the addition of two or more waves superposition that results in a new ave pattern
interference
13 of 18
two waves with a constant phase relationship
coherence
14 of 18
a point that always had zero amplitude along a stationary wave caused by destructive interference
nodes
15 of 18
a point of maximum amplitude along a stationary wave caused by constructive interference
antinodes
16 of 18
whole number multiples of the fundamental frequency of a stationary wave
harmonics
17 of 18
the difference by which one wave leads or lags behind another
phase difference
18 of 18
