A wave that need a medium to travel through

Mechanical wave

3

Electromagnetic spectrum

RADIO WAVES
MICROWAVES
INFRARED RAYS
VISIBLE LIGHT

4

the highest point on a wave.

Crest

5

is the lowest point.

Trough

6

The distance from crest to crest or trough to trough in a wave.

Wavelength

7

The distance from the resting point to the crest of a wave.

Amplitude

8

A wave in which the energy travels perpendicular to the direction of the disturbance.

Transverse wave

9

is the peak (greatest) value (either positive or negative) of a wave. The distance from the undisturbed level to the trough or crest.

Amplitude

10

is the part of the compressional wave where the particles are spread apart.

Rare fraction

11

When waves strike a surface and bounce back in another direction.

Reflection

12

Waves spread out as a result of passing through a narrow aperture or around an edge of material

Diffraction

13

The number of waves that pass a given point in a set period of time.

Frequency

14

A wave in which the energy travels in the same direction as the disturbance.

Longitudinal wave

15

The point in a longitudinal wave where the matter is pushed closer together.

Compression

16

The bending of waves as they pass through a material

Refraction

17

The distance between one point on a wave and the exact same place on the next wave.

Wavelength

18

does NOT carry matter with it! It just moves the matter as it goes through it.

Wave

19

Waves in which the medium moves at right angles to the direction of the wave

Transverse wave

20

Waves in which the medium moves back and forth in the same direction as the wave

Compressional wave

21

How far the medium moves from rest position

Amplitude

22

Waves can bend.

Refraction

23

The bending of waves AROUND an object.

Diffraction
