wave Flashcards
What type of wave moves at right angles or perpendicular to the direction that
it travels?
transverse
Which of the following is NOT a
type of electromagnetic wave?
a. X-ray
b. infrared
c. radio waves
d. sound
d. sound
What types of waves require a medium through
which to travel?
mechanical
If wavelength is doubled, then
frequency is:
a. doubled.
b. halved.
c. unchanged.
d. quadrupled.
b. halved
The number of waves passing
a given point each second is:
a. frequency
b. wave speed
c. wavelength
d. amplitude
a. frequency
The _____________
of a wave is a
direct measure of its energy.
a. frequency
b. wave speed
c. wavelength
d. amplitude
D. amplitude
What is the matter through which a wave
travels called?
medium
Why do sound waves travel faster in liquids
or solids than in air?
the particles in a solid and liquid are closer together so they compress and expand faster
What type of wave is a sound
wave?
a. transverse and mechanical
b. transverse and electromagnetic
c. longitudinal and mechanical
d. longitudinal and electromagnetic
C. longitudinal and mechanical
A wave is a
disturbance that
transfers ___________
from
one place to another.
energy
What type of wave moves back and forth parallel to the direction
that it is traveling?
longitudinal
compression
What types of waves can travel through empty space as well as
through matter?
Electromagnetic
Which of the following is NOT
true about mechanical waves?
a. They carry energy.
b. They transfer matter.
c. They can be longitudinal.
d. They require a medium.
b. they transfer matter
As a wavelength decreases,
the crests of the wave:
a. become wider.
b. become shorter.
c. get closer together.
d. get farther apart.
c. get closer together
A substance that transmits a sound wave is called a __________.
medium
The particles of the medium in a TRANSVERSE wave vibrate in a direction __________ to the directions that the wave moves. (Hint: Stadium Wave)
perpendicular
True or False. When a compression wave travels through a medium, the medium moves with the wave. (Hint: This is NOT referring to the particles)
false
How are electromagnetic waves different from mechanical waves?
they can only travel through space
What is the difference between a compression and a rarefaction?
Compressions are high pressure areas while rarefactions are low pressure areas
Water is an example of which type of wave?
transverse
True or Flase. We can hear sound in space.
false
The particles of the medium in a LONGITUDINAL wave vibrate in a direction __________ to the directions that the wave moves. (Hint: Slinky)
parallel
Rythmic disturbance which transmits energy through matter and space
wave
Which is an example of a Mechanical Wave?
sound wave
Sound waves can travel through which type(s) of mediums?
Solids, Liquids, and Gases
waves carry ________?
energy
How can I find the wavelength of a longitudinal wave?
Compression to Compression OR Rarefaction to Rarefaction
How can you find the wavelength of a transverse wave?
crest to crest or trough to trough
A disturbance that transmits energy through matter BUT requires a medium for the wave to travel through
mechanical waves
Sound is an example of what time of wave?
longitudinal
What is required for a mechanical wave to travel through?
medium
This is the greatest distance that particles in a wave rise or fall from their rest position (distance from “rest to crest”); the amount of energy the wave carries
amplitude
transverse =
perpendicular
longitudinal =
parallel
True or False. Higher the amplitude, the more energy a wave has.
true
