Waves

Question 1

Wave

Answer 1

Repeating distance or movement that transfers energy through matter and space. (Medium)

Question 2

Medium

Answer 2

Substance or material which carries the wave.

Question 3

Crest

Answer 3

Top of wave

Question 4

Trough

Answer 4

Bottom of wave

Question 5

Node

Answer 5

Place where the wave meets the Rest Position.

Question 6

Rest Position

Answer 6

Line through a wave.

Question 7

Amplitude

Answer 7

Distance from resting position.

Question 8

Wavelength

Answer 8

The distance from the top of one crest to the top of the next crest. OR node to every other node.

Question 9

Transverse Wave

Answer 9

Motion of the medium is at right angles to the direction or travel (Opposite of each other)
EX: Ocean Waves

Question 10

Longitudinal aka Compression wave

Answer 10

Particles move along the direction of the wave.

EX: Sound

Question 11

Compression

Answer 11

Dense region of compression wave.

Question 12

Rarefication

Answer 12

Less dense region of compression wave.

Question 13

Frequency

Answer 13

of wavelengths that pass a certain point in a certain amount of time

Question 14

Sound

Answer 14

Energy carried by vibration of matter

Question 15

Intensity

Answer 15

Amount of energy that flows through a certain area in a specific amount of time

Question 16

Loudness

Answer 16

Human perception of sound

More energy aka amplitude=more loudness

Question 17

Decibels (dB)

Answer 17

Measurement of sound

Question 18

Pitch

Answer 18

Our perception of how high or low a sound’s frequency (# of wavelengths) is
