1

Pulse

Single disturbance in a wave the moves from one direction to another

2

Transverse pulse

Occurs when particles move perpendicular to the sources direction

3

Frequency

F , cycles per second measures in hertz Hz

4

Period

T seconds per cycle measured in seconds

5

Constructive interference

Two pulses meet at the same point and the amplitudes are then added together

6

Interference

Two or more pulses are at th same point in the same place and at the same time

7

Destructive interference

When two pulses or waves meet at the same point in the same medium they superimpose on each other to creat a lower amplitude

8

amplitude

Maxim displacement of a particle in a medium Ym

9

Phase

Is related to the particles and there position on the medium

10

Wave length

Shortest point between two points that are in phase

11

Longitudinal wave

Disturbance of medium is proportionate to the propagation direction
! )) )) ))

12

Condensation / compression

)))) when pressure is created through a medium
Peak

13

Rarefaction

Space between compression
Trough

14

Angle of incident

Angle that sound hits hard surface is equal to the trajectory

15

Reverberation

Echoed

16

Pitch

Determined by frequency

17

Distance

The Length of the actual path

18

Displacement

Change in position of the object

19

Scaler

Has magnitude

20

Vector

Has magnitude and direction

21

Acceleration

Rate of change in velocity

22

Superposition

When two waves or pulses meet in the same medium at the same time
