Sound

Question 1

Transverse wave

Answer 1

a wave vibrating at right angles to the direction the wave is traveling

Question 2

Trough

Answer 2

The lowest point of the wave

Question 3

Wavelength

Answer 3

Distance from top of the crest to the top of the next one

Question 4

Crest

Answer 4

High point of a wave

Question 5

Out of phase

Answer 5

The overlapping of two waves such that the crest of one is aligned with the eh trough of another

Question 6

Doppler effect

Answer 6

The change in pitch heard when an object is emitting a sound and moving moving toward or away from the listener

Question 7

How are constructive and destructive interference similar and different ?

Answer 7

Similar : both lead to change in amplitude

Different : constructive interference has a increase in amplitude

Destructive interference amplitude cancels out

Question 8

In phase

Answer 8

Occurs when two waves overlap

Question 9

What is the range of human hearing ?

Answer 9

20-20,000

Question 10

Amplitude

Answer 10

Height of the wave from zero

Question 11

Answer 11

Occurs when the frequency of a force vibration matches the natural frequency of the body

Question 12

Compression

Answer 12

When they come together

Question 13

Rarefaction

Answer 13

When it spreads out less force

Question 14

What’s is the unit for frequency

Answer 14

Hertz

Question 15

What is the units for wavelength

Answer 15

Cm/ s m/s

Question 16

What is the unit fors for period

Answer 16

Seconds

Question 17

What is the untie for velocity

Answer 17

Meters

Question 18

What media can sound move through the fastest

Answer 18

A solid

Question 19

What media can sound move after the fastest media ?

Answer 19

Liquid

Question 20

What media can sound move through the slowest

Answer 20

Gas

Question 21

What media can sound out move through and why

Answer 21

A vacuum , a space where there is no air . Can not be transmitted bc there is no air .

Question 22

Similarities / difference between a transverse wave and a longitudinal wave ?

Answer 22

Similar

Difference:direction the medium of the wave moves
Longitudinal- the motion of the medium is parallel to the direction of the wave . This means that the particles move left and right

Transverse the motion of the medium is a right angles to the direction of the wave.

Question 23

Constructive interference

Answer 23

When the a crest of one waves overlaps a crest of another wave to produce a wave of increase of amplitude

Question 24

Destructive wave

Answer 24

A combination of waves here crests of one overlaps the trough of another causing the wave To have a decrease in amplitude

Question 25

Nodes(standing wave )

Answer 25

Any part of a standing wave that remains stationary

Question 26

Antinodes (standing wave)

Answer 26

The position on a standing wave where the largest amplitudes occurs

Question 27

Ultra sonic

Answer 27

To high for you to hear

Question 28

Intra sonic

Answer 28

To low for you to hear

Question 29

The difference in size and mass between and mass between instruments

Answer 29

Frequency increases -- pitch decreases High pitch --- high frequency Higher the mass --- lower the pitch Shorter the air column ---higher the pitch Lower pitch --- low frequency

Question 30

Stadium wave

Answer 30

A pulse that moves through the crowd at sporting events

Question 31

Shock wave

Answer 31

A cone shaped wave produced by an object moving at supersonic speed through a fluid

Question 32

A longitudinal and compressional wave

Question 36

Frequency

Answer 36

The number of cycles per second that a sound makes .

Question 37

Period

Answer 37

Amount of time per cycle

Question 38

Natural frequency

Answer 38

The standard frequency at which an object vibrates when struck, plucked, bowed or blown into

Question 39

Refraction

Answer 39

Change in speed of wave when it | Moves from one medium to another

Question 40

Medium

Answer 40

A substance that carries a wave from one location to another

Question 41

What happen to Tacoma narrows bridge in 1940 at Washington ?

Answer 41

It was destroyed by a 40 mph wind. The wind produced a forced that resonated with natural frequency of the bridge . The amplitudes for higher and higher over several hours and collapsed

Question 42
