0

A periodic disturbance that moves away from a source and carries energy with it

wave

1

the direction of the wave is perpendicular to the direction of the particle displacement

transversal wave

2

the direction of the wave is parallel to the directino of the particle

longitudinal wave

3

height of the wave

amplitude

4

highest point of the wave

crest

5

lowest point in the wave

trough

6

distance between adjacent crests or troughs

wavelength

7

formula for frequency

v (wave speed)/ wavelength = f

8

formula for speed v (velocity)

v = square root of (Tension)/(mass/length)

9

two pulses moving in opposite directions along a stretched string

principle of superposition

10

harmonic wave

graph of y=sin x

11

wave function

y = f(x-vt)

12

the addition of energy to a system of some kind by a periodic source that varies with a frequency equal to one of the systems natural frequencies of vibration

resonance
