An object that does not vibrate cannot produce
Sound
Light
Heat
Electricity
A place where no sound exists is...
in the air.
under water.
space.
all of the above
Why do we see lightning before we hear the thunder?
Our eyes trick us.
Light travels faster than sound.
they're two separate things.
What is Pitch?
How loud or soft a sound is.
Muscle that holds vocal cords.
Movement back and forth.
How high or low a sound is.
____________ is determined by sound's frequency
Compression
Pitch
A sound with a high frequency has a _____ pitch. A sound with a ____ frequency has a low pitch.
high, low
low, high
medium, high
high, medium
A disturbance that transfers energy from one place to another without transferring matter
What is the Doppler Effect
Where the wavelength of a wave is shifted due to the source moving
When a wave is shifted when a body pushes the wave
Where the apparent wavelength of a wave is shifted due to the source moving
An observer moves towards a source of sound at a speed of 30 ms-1
If the frequency of the sound to a stationary observer is 500 Hz the frequency to the moving observer is
456 Hz
544 Hz
460 Hz
325 Hz
Lance and Kasi conduct an activity using a slinky. Lance fixes one end of the slinky against a fixed support. He then moves the slinky back and forth, as shown.
Kasi sees the wave moving towards the fixed support. What is true for this mechanical wave?
It transmits energy only
It transmits matter only
It transmits both matter and energy
It transmits both energy and a medium
What kind of wave requires the particles of a medium to vibrate and transfer energy?
infrared light wave
Radio Wave
Seismic Wave
Visible light wave
An undersea earthquake centered 1000 miles off the coast of Hawaii creates a tsunami headed toward the Hawaiian coast. This tsunami encounters a fishing boat 500 miles from the coast. What will happen to the boat?
The tsunami will pick up the boat at its current position and carry the boat on its crest all the way into the coast.
The tsunami will carry the boat toward the coast for many miles, but because the boat is so large, the wave canot carry it all the way to shore.
The boat will be lifted up as the wave passes beneath it, and then be pushed many miles from the coast.
The boat will bob up and down as the wave passes beneath it, but the wave will not carry the boat either toward or away from shore.
Two sound waves of different frequencies interfere and produce a resulting waveform shown with four points (W, X, Y, and Z) marked on the new wave.
At which point will the sound be the loudest ?
W
X
Y
Z
The diagram shows a research vessel using sonar to map the ocean floor.
Upon which basic behavior of sound waves does this technology depend?
absorption
compression
reflection
refraction
A boy has a cork on his fishing line in a lake. His brother throws a rock in the lake near where he is fishing, and the waves created from the rock splashing cause the boy's cork to bob up and down for over a minute. What is the medium for the waves in this scenario?
the cork
the water
the rock
the fishing line
Through which medium is it impossible to transmit sound waves?
space
rock
air
water
Which of these is not a property of a sound wave?
intensity
elasticity
loudness
pitch
The apparent change in frequency as a wave source moves in relation to the listener is the ___________.
Doppler Effect
Doppler Radar
Doppelganger
