Introduction To Waves

Question 0

Vibration

Answer 0

Side to side or up and down motion

Question 1

Wave

Answer 1

A disturbance that transfers energy from one place to another
The matter inside of a wave does not travel

Question 2

Mechanical Wave

Answer 2

A wave that needs matter to travel through

• Water
• Earthquake
• Sound

Question 3

Electromagnetic Wave

Answer 3

A wave that transfers energy through a field

• Visible light
• Infrared light
• Radio waves

Question 4

Field

Answer 4

The area around an object that can exert force

Question 5

Wavelength

Answer 5

Crest to crest

Question 6

Amplitude

Answer 6

Middle to top of crest

Question 7

Frequency

Answer 7

The amount of waves that pass through a certain area during an amount of time
1 wave/10 seconds

Question 8

Crest

Answer 8

The top of a wave

Question 9

Trough

Answer 9

The bottom of a wave

Question 10

Transverse Wave

Answer 10

Waves that travel perpendicularly to the force that creates it
(Mechanical)

Question 11

Longitude/Compression Waves

Answer 11

A wave that travels in the same direction as the force that created it
(All sound and mechanical)

Question 12

Area of Compression

Answer 12

The “crest,” of a longitude/compression wave

Question 13

Area of Rarefaction

Answer 13

Area where the frequency of waves is less on longitude/compression waves

Question 14

Reflection

Answer 14

The bouncing back of a wave when it hits a barrier

Area of incident, area of reflection

Question 15

Refraction

Answer 15

The bonding of a wave when it passes from one type of matter to another

Question 16

Diffraction

Answer 16

When a wave passes through an opening and spreads out

Question 17

Interference

Answer 17

When two waves interact with each other

• Constructive
• Destructive
