Flashcards in Waves Deck (30):
1

Wave

A disturbance that transfers energy from one place to another without matter to travel the entire distance

2

Medium

A substance through which a wave moves

3

Mechanical Wave

A wave such as a sound or seismic wave that transfers kinetic energy through matter

4

Transverse Wave

A wave in which the disturbance moves at right angles to the direction of the wave

5

Longitudinal Wave

A type of wave in which the disturbance moves in the same direction that the wave travels

6

Crest

The highest point or peak in a wave

7

Trough

The lowest point in a wave

8

Amplitude

The maximum distance that a disturbance causes a medium to move from its rest position

9

Wavelength

The distance from one crest to the next wave crest

10

Frequency

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

11

Reflection

The bouncing back of a wave after it hits a barrier

12

Refraction

The bending of light at it crosses a boundary between two mediums at an angle other than 90 degrees

13

Diffraction

The spreading out of waves as they pass through an opening or around the edges of an obstacle

14

Interference

The meeting and combining of waves; the adding or subtracting of wave amplitudes that occur as waves overlap

15

Electromagnetic Waves

A type of wave such as a light wave or radio wave that does not require a medium to travel through a disturbance that transfers energy through a field

16

Radiation

Energy that travels across distances in the form of electromagnetic waves

17

Electromagnetic Spectrum

The range of all electromagnetic frequencies

18

Radio waves

The part of the electromagnetic Spectrum that consists of waves of the lowest frequencies

19

Microwaves

Part of the electromagnetic Spectrum that consists of waves with a higher frequencies than radio waves but peer frequencies than infrared waves

20

Infrared Light

Part of the electromagnetic Spectrum that consists of waves with a frequencies between those of microwaves and visible light

21

Ultraviolet Light

The part of the electromagnetic Spectrum that consists of wave of frequencies higher than those of visible light and lower than x-rays

22

X-Rays

The part of the electromagnetic Spectrum that consists of waves with high frequencies and high energies;electromagnetic wave with frequencies ranging from 10 to the 16th power to the 21st power of hertz

23

Gamma rays

Part of the electromagnetic Spectrum that consists of waves with the highest frequencies

24

Transmissions

The passage of waves through a medium

25

Absorption

The disappearance of a wave into a medium. The energy transferred by a wave is converted into another form of energy

26

Scattering

The spreading out of light waves in all directions as particles reflect and absorb the light

27

Polarization

The way of filtering light so that all of the waves vibrate in the same direction

28

Prism

An optical tool that uses refraction of light to separate the different wavelengths that make up white light

29

Primary colors

The colors of light (red, yellow and blue)that can be mixed to produce all possible colors

30

Primary pigments

The color of all substances (cyan, yellow, and magenta) that can be mixed to produce any possible colors
