Answer 1

wave

Question 2

When undisturbed the matter the wave travels through is its

Answer 2

equilibrium or point of rest

Question 3

A single disturbance that moves outward

Answer 3

pulse

Question 4

a series of pulses

Answer 4

wave

Question 5

type of matter a wave travels through

Answer 5

wave medium

Question 6

Waves transfer energy not

Answer 6

matter

Question 7

Waves that travel through matter need a medium

Answer 7

mechanical waves

Question 8

Two types of waves

Answer 8

transverse & longitudinal

Question 9

highest part of a wave

Answer 9

crest

Question 10

lowest part of a wave

Answer 10

trough

Question 11

distance between each wave (from crest to crest or from trough to trough)

Answer 11

wavelength

Question 12

max. distance a point is moved

Answer 12

amplitude

Question 13

particles vibrate parallel or in the same direction of the disturbance

Answer 13

longitudinal wave (compression wave)

Question 14

areas of high pressure that is created as vibrating objects move forward

Answer 14

compressions

Question 15

areas of low pressure that’s created when the vibrating object moved backwards

Answer 15

rarefractions

Question 16

the greater the compression the greater the

Answer 16

amplitude

Question 17

the period (T) of a wave is defined as

Answer 17

the time it takes for one vibration of one full wavelength to pass

Question 18

the number of vibrations a wave makes per second

Answer 18

frequency

Question 19

how many waves pass a point per second

Answer 19

frequency

Question 20

relationship between frequency and period

Answer 20

inverse

Question 21

if speed is constant shorter wavelengths have

Answer 21

higher frequencies

Question 22

if speed is constant longer wavelengths will have

Answer 22

lower frequencies
