Chapter 20 Major Quiz

Question 0

what affects frequency?

Answer 0

rate of propogation (the rate at which you create a wave vibration)

Question 1

what affects wavelength?

Answer 1

frequency and wave speed

Question 2

what affects period?

Answer 2

frequency

Question 3

what affects wave speed?

Answer 3

properties of the medium

Question 4

what affects amplitude?

Answer 4

the amount of energy applied to the wave

Question 5

how many cycles are created in a certain time period

Answer 5

frequency (Hz)

Question 6

the time it takes to complete one cycle; has to end in the same place it starts

Answer 6

Period (T)

Question 7

when some outside force (air resistance, etc.) takes energy outside of the system and makes the simple harmonic motion less extreme; reduces the amplitude of a wave

Answer 7

dampening

Question 8

a repetitive motion caused by a restoring force that will keep moving forever in an ideal world

Answer 8

simple harmonic motion

Question 9

a wave that requires a medium, or some physical object, to travel through (ex: sound)

Answer 9

mechanical waves

Question 10

waves that can travel through space (ex: light, microwaves, x-Rays, gamma rays, radio waves)

Answer 10

electromagnetic waves

Question 11

a wave in which the medium travels perpendicular to the path of energy

Answer 11

transverse wave

Question 12

a wave in which the medium travels parallel to the path of energy

Answer 12

longitudinal

Question 13

a means of transporting energy from one place to another

Answer 13

wave

Question 14

the distance between two crests or two troughs (transverse) or two compressions or two rarefactions (longitudinal); one wave cycle

Answer 14

wavelength

Question 15

distance from crest to midline or midline to trough

Answer 15

amplitude

Question 16

graphical representation of wave-like motion

Answer 16

sine wave

Question 17

what happens when a wave pulse hits a boundary?

Answer 17

it reflects back on the opposite side of the midpoint

Question 18

what happens when a wave pulse hits a loose end?

Answer 18

it reflects back on the same side of the midpoint

Question 19

when two identical parts of a wave are in the same place at the same time

Answer 19

constructive interference

Question 20

a type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction (a crest and a trough meet)

Answer 20

Destructive interference

Question 21

what affects the period of a pendulum?

Answer 21

Length of the pendulum

Question 22

what affects the period of a mass on a spring?

Answer 22

mass and spring constant

Question 23

the lowest frequency that creates a standing wave within a certain boundary or length

Answer 23

fundamental frequency

Question 24

appears to stand still

Answer 24

standing wave

Question 25

appears to travel from one place to the other

Answer 25

traveling wave

Question 26

when you have constructive interference and destructive interference in the same place at the same time repetitively; the crest of each wave cancels with the trough of the previous one

Answer 26

what causes standing waves?

Question 27

point of minimum displacement or no displacement on a standing wave

Answer 27

node

Question 28

two points of maximum displacement on a standing wave

Answer 28

antinode
