Question 4

Absorption

Answer 4

The disappearance of an EM wave through a medium

Question 5

Medium

Answer 5

Any substance that a wave moves through

Question 6

Mechanical Waves

Answer 6

Waves that transfer energy through matter

Question 7

Transverse Wave

Answer 7

A wave that has been set off horizontal or forward of the disturbance

Question 8

Longitudinal Wave

Answer 8

A wave that travels in the same direction as the disturbance

Question 9

Crest💡

Answer 9

The highest point or peak of the wave

Question 10

Trough

Answer 10

The lowest point or valley of the wave

Question 11

Amplitude

Answer 11

The distance between the middle point of the wave and the crest or trough

Question 12

Wavelength

Answer 12

The distance between one crest and the next or one trough and the next

Question 13

Frequency

Answer 13

The number of waves passing a certain point in a certain amount of time

Question 14

Diffraction

Answer 14

The spreading out of waves through an opening or around the edge of an obstacle

Question 15

Interference

Answer 15

The meeting and combining of waves

Question 16

Electromagnetic Spectrum (or EM spectrum)

Answer 16

The range of EM frequencies

Question 17

Radio Waves

Answer 17

EM waves that have the longest wavelengths the lowest frequencies and the lowest energies

Question 18

Microwaves

Answer 18

EM waves with shorter wavelengths higher frequencies and higher energies than radio waves

Question 19

Visible light

Answer 19

The part of an EM spectrum that human eyes can see

Question 20

Ultraviolet light

Answer 20

part of the EM spectrum consisting of frequencies above those of visible light and particularly below those of x-rays

Question 21

X-rays

Answer 21

Have frequencies between about 10 to the sixteenth power Hz to 10 to the twenty-first power Hz. Produced by the sun and other stars.

Question 22

Gamma rays not on test

Answer 22

Frequencies from 10 to the 19 power Hz to 10 to the 24 power Hz. Produced by the sun and by other stars.

Question 23

Scattering

Answer 23

The spreading out of light rays in all directions because particles reflect and absorb the light.

Question 24

Polarization

Answer 24

A quality of light in which all of its waves vibrate in the same direction

Question 25

Prism

Answer 25

A tool that uses refraction to spread out the different wavelengths that make up white light

Question 26

Primary colors

Answer 26

Three colors(red blue and yellow) that can be mixed together to make all possible colors

Question 27

Primary pigments

Answer 27

Pigments (cyan yellow and magenta) that you can mix together to produce all colors just as the primary colors

Question 28

Waves

Answer 28

A disturbance that transfers energy from one place to another.

Question 29

Radiation

Answer 29

Energy that travels across distances in the form of electromagnetic waves

Question 30

Infrared light

Answer 30

parts of the electromagnetic spectrum that consists of wave of frequencies higher than those of visible light and lower X-rays
