Chapter 4 Waves

Question 0

energy.

Answer 0

is the capacity to apply a force over a distance

Question 1

does a wave transfer energy or matter.

Answer 1

a wave transfers energy forward

Question 2

force

Answer 2

is a push or pull on an object

Question 3

equilibrium is?

Answer 3

rest position

Question 4

rest position is?

Answer 4

the level of water where there is no waves.

Question 5

a crest

Answer 5

the top or highest point of a wave

Question 6

a trough

Answer 6

is the lowest point in a wave

Question 7

wavelength is?

Answer 7

the distance between crest to crest or trough to trough or two exact point in to waves.

Question 8

what is wavelengths measured by?

Answer 8

meters

Question 9

what is amplitude?

Answer 9

amplitude is height or depth of the rest position to the trough or the crest.

Question 10

the greater the amplitude the greater the…..

Answer 10

energy transported

Question 11

i light wave with a large amplitude carries more energy would this be a bright light or a dim light?

Answer 11

it would be a bright light with a bigger amplitude and energy.

Question 12

what is frequency?

Answer 12

frequency is the number of repetitive motions, or oscillations, that ocur in a given time.

Question 13

frequency is usually measured in….

Answer 13

hertz (Hz) which mans cycles per second

Question 14

the shorter the wave the greater the….

Answer 14

frequency (when one increases the other decreases)

Question 15

what is a medium?

Answer 15

the medium is a solid, liquid, or gas or a combination of these.

Question 16

what are the two types of waves that travel through a medium?

Answer 16

transverse waves and compression waves

Question 17

tansverse waves matter in the medium moves…

Answer 17

up and down (shaking a rope)

Question 18

in a compression waves matter in the medium moves…

Answer 18

back and forth along the same way the wave travels.
