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
