waves

Question 1

wave

Answer 1

a repeating disturbance or movement that transfers energy through matter and space (medium)

Question 2

medium

Answer 2

anything that a wave can travel through

Question 3

Crest

Answer 3

high point of a wave

Question 4

trough

Answer 4

low part of a wave

Question 5

rest position

Answer 5

mid point of a wave

Question 6

node

Answer 6

marks beginning and end of waves

Question 7

amplitude

Answer 7

how high up and how low the wave goes from the rest position

Question 8

wavelength

Answer 8

the distance from the top of one crest to the top of the next crest

or node to the next node

Question 9

transverse waves

Answer 9

motion of the medium is at right angles to the direction of travel

ex. tidal wave

Question 10

longitudinal (compression wave)

Answer 10

wave that particles move along the direction of the wave

Question 11

compression

Answer 11

a compression is a dense region of a longitudinal wave

Question 12

rarification

Answer 12

less dense area of a wave

Question 13

frequency

Answer 13

number of wavelengths in one seccond

Question 14

sound

Answer 14

longitudinal waves that travel through a medium

Question 15

intensity

Answer 15

how tall the waves are in sound

Question 16

loudness

Answer 16

our perception of intensity

Question 17

Decibles

Answer 17

measurement of how intense sound waves are

Question 18

Pitch

Answer 18

out perception of how high or low a sound is
