does a wave transfer energy or matter.

a wave transfers energy forward

1

energy.

is the capacity to apply a force over a distance

2

force

is a push or pull on an object

3

equilibrium is?

rest position

4

rest position is?

the level of water where there is no waves.

5

a crest

the top or highest point of a wave

6

a trough

is the lowest point in a wave

7

wavelength is?

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

8

what is wavelengths measured by?

meters

9

what is amplitude?

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

10

the greater the amplitude the greater the.....

energy transported

11

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

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

12

what is frequency?

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

13

frequency is usually measured in....

hertz (Hz) which mans cycles per second

14

the shorter the wave the greater the....

frequency (when one increases the other decreases)

15

what is a medium?

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

16

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

transverse waves and compression waves

17

tansverse waves matter in the medium moves...

up and down (shaking a rope)

18

in a compression waves matter in the medium moves...

back and forth along the same way the wave travels.
