1

Wave

The transfer of energy without transferring matter

2

Mechanical Wave

A wave of which needs a matter or medium to travel through

(Sound, Ripple, Sports Wave)

3

Electromagnetic Wave

An Electromagnetic Wave is a wave that does not need a matter to travel through

(Radio, Microwaves, Infrared, Visible Light, UV, X-rays, Gamma)

4

Parts of the spectrum

Radio wave, Microwave, Infrared, Visible Light, Ultraviolet, X-rays, and Gamma rays

5

Radio Waves, and Microwaves

Radio and Microwaves can both be used for communication, but Microwaves are better because they have a higher energy. Also, they can be used for cooking

6

Infrared and Visible Light

Infrared can be used for thermal energy. Visible Light can be used for seeing everything. The colors of the rainbow (ROY G. BIV) are all based off of the Visible Light.

7

Ultraviolet Rays and X-rays

Ultraviolet Rays can be used for killing bacteria. When someone gets extremely sick, this Ray is used. X-rays can be used for seeing bones. Also, it is used by construction workers to see cracks in structures.

8

Gamma Rays

Gamma Rays are mainly used for killing bad cells. When a person gets cancer, these Rays are used to kill the cells, but they can also kill good cells.

9

Crest

The highest point of a wave

10

Trough

The lowest point of a wave

11

Period

The time for a complete cycle to pass a given point.

12

Wavelength

The distance from crest to crest or trough to trough (meters)

(Compressional-compression to compression)

13

Amplitude

The distance between the crest to the resting point of a wave

14

Frequency

The number of waves that pass a given point in a set period of time
(Hertz)

15

Longitudinal Wave

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

16

Compression

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

(Sound Wave, Sliky)

17

Rarefaction

The point in a longitudinal wave where the matter is spaced farther apart

18

Transverse Wave

A wave in which the energy travels perpendicular to the disturbance (or right angles)

19

Reflection

When waves strike a surface and bounce back in another direction

20

Refraction

The bending of waves when they pass through materials

21

Diffraction

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

22

Wavespeed

Frequency times wavelength
(Meters per second)

23

Frequency

Speed divided by wavelength
(Hertz)

24

Wavelength

Speed divided by frequency
(Meters)
