How do sound waves travel through air as a medium?
Air is pushed back and forth toward and away from the source of the sound.
What happens when a mechanical wave travels through a medium?
Energy is transferred
Which is true about a surface wave?
It has properties of both transverse and longitudinal waves.
Which is true of a mechanical wave?
It must have a medium.
Which of the following is true of mechanical waves?
Mechanical waves have repeating patterns.
Which of these is NOT true of periodic waves?
Periodic waves do not have a distinct pattern.
Which is true about surface waves?
The disturbance is in a circular motion.
When a wave passes through a medium, how do particles in the medium move?
The particles in the medium stay in about the same place.
Which of these has an observable repeating wave pattern?
a flag fluttering in the wind
A wave pulse is
a single disturbance that does not repeat.
Which kind of wave(s) carry energy from one place to another?
all mechanical waves.
In a mechanical wave, the particles of matter move ______ & ______.
back & forth
What is the resulting direction of a surface wave?
circular
What kind of pattern of motion would you expect to see in a surface wave?
circular motion
Which of these is an example of a longitudinal wave?
coils being pulled and pushed in a spring
Rather than troughs and crests, longitudinal waves have
compressions and rarefactions
A wave's ______ is the highest point in the S-shape.
crest
A wave is a disturbance that carries
energy from one place to another.
Which of the following does NOT create a mechanical wave?
light coming through a window
Sound waves are _____ waves.
longitudinal
A wave in which the particles move along a path that is parallel to a wave's direction is a
longitudinal wave.
The matter that a mechanical wave travels through is called a ____________.
medium
A representation of a situation which makes important aspects easy to see
model
Surface waves are usually found where?
near the surface of a medium
A transverse wave looks like a series of S-shapes because
of the periodic motion of the matter.
A wave cycle is
one complete motion of the repeating pattern in a wave.
The forward and backward motions in a surface wave move in a direction ______ to the direction the wave travels.
parallel
Unlike a transverse wave, the disturbance in a longitudinal wave is
parallel to the wave motion.
When on a flat surface, giving the Slinky® a push or pulse will create a disturbance
parallel to the wave motion.
A transverse wave is a wave in which the particles move in a pattern _______ to the direction the wave travels.
perpendicular
Unlike a longitudinal wave, the disturbance in a transverse wave is
perpendicular to the wave motion.
Longitudinal
side to side.
. A trough is
the lowest point of a wave.
Which of these is the medium for a shaking jump rope?
the rope
Which type of wave has a wave perpedicular to the disturbance?
transverse
A wave of bees like a hand wave is....
transverse.
perpendicular direction
up and down
A transverse wave can be created in a Slinky® by moving it
up and down.
One complete motion of the repeating pattern of a wave = _________
wave cycle
A wave made of a single disturbance that does not repeat is called a ________.
wave pulse
