Question 1

Medium

Answer 1

A substance through which a wave moves

Question 2

Mechanical wave

Answer 2

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

Question 3

Transverse wave

Answer 3

A type of wave in which the disturbance moves at right angles , or perpendicular, to the direction in which the wave travels

Question 4

What is the definition of the word wave ?

Answer 4

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

Question 5

Longitudinal wave

Answer 5

A wave that travels in the same direction as the disturbance.

Question 6

Crest

Answer 6

Highest point or peak of a wave

Question 7

Trough

Answer 7

Lowest point or valley of a wave

Question 8

Amplitude

Answer 8

The distance a medium moves above or below its position at rest

Question 9

Wavelength

Answer 9

Distance from one crest or trough to the next

Question 10

Frequency

Answer 10

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

Question 11

Reflection

Answer 11

The bouncing back of a wave after it strikes a barrier

Question 12

Refraction

Answer 12

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

Question 13

Diffraction

Answer 13

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

Question 14

Interference

Answer 14

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

Question 15

Electromagnetic wave

Answer 15

A disturbance that transfers energy through a field

Question 16

Radiation

Answer 16

Energy that travels across distances in the form of electromagnetic waves

Question 17

Electromagnetic spectrum

Answer 17

The range of all electromagnetic frequencies

Question 18

Radio waves

Answer 18

The part of the electromagnetic spectrum that consists of waves with the lowest frequencies

Question 19

Microwaves

Answer 19

Part of the electromagnetic spectrum that consists of waves with higher frequencies than radio waves but lower frequencies than infrared waves

Question 20

Ultraviolet light

Answer 20

The part of the electromagnetic spectrum that consists of waves with frequencies higher than those of visible light and lower than those of x-rays

Question 21

Gamma rays

Answer 21

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

Question 22

Transmission

Answer 22

The passage of a wave through a medium

Question 23

X-rays

Answer 23

The part of the electromagnetic spectrum that consists of waves with high frequencies and high energies

Question 26

Absorption

Answer 26

The disappearance of a wave into a medium . When a wave is absorbed, the energy transferred by the wave is converted into another form of energy, usually thermal energy

Question 27

Scattering

Answer 27

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

Question 28

Polarization

Answer 28

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

Question 29

Prism

Answer 29

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

Question 30

Primary colors

Answer 30

Three colors of light - red, green , blue- that can be mixed to produce all possible colors

Question 31

Primary pigments

Answer 31

Three colors of substances - cyan, yellow , and magenta - that can be mixed to make all possible colors

Question 33

Infrared light

Answer 33

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

Question 35

Visable light

Answer 35

The part of the electromagnetic spectrum that consists of waves detectable by the human eye
