waves

Question 1

wave

Answer 1

a disturbance involving the transfer of energy from place to place

Question 2

medium

Answer 2

the material through which a wave travels

Question 3

mechanical wave

Answer 3

waves that require a medium

Question 4

transverse wave

Answer 4

a wave that vibrates the medium at right angles or perpendicular to the direction in which the wave travels

Question 5

crest

Answer 5

high point on a transverse wave

Question 6

trough

Answer 6

low point on a transverse wave

Question 7

longitudinal/compressional wave

Answer 7

vibrates the medium in the same direction in which the wave travels

Question 8

compression

Answer 8

particles are close together on a longitudinal wave

Question 9

rarefaction

Answer 9

particles are far apart on a longitudinal wave

Question 10

amplitude

Answer 10

the maximum distance the medium vibrates from the rest position

Question 11

wavelength

Answer 11

he distance from any point on a wave to an identical point on the next wave

Question 12

frequency

Answer 12

number of waves that pass a point in a certain amount of time

Question 13

doppler effect

Answer 13

refers to the change in wave frequency during the relative motion between a wave source and its observer.

Question 14

pitch

Answer 14

higher or lower in pitch according to the frequency of vibration of the sound waves producing them.

Question 15

loudness

Answer 15

depends on the amplitude of the sound wave involved.

Question 16

resting position

Answer 16

the undisturbed position of particles when they are not vibrating.

Question 17

electromagnetic wave

Answer 17

does not require a medium, can travel through empty space
