what is the difference between a transverse wave and a longitudinal wave?
traverse waves: particles move perpendicular to the wave longitudinal waves: the particles move parallel to the wave
100
Term that refers to how high or low sound frequency appears to be.
What is pitch
100
what is the speed of light
800,000 km/s
100
True or false: loudness of sound is objective
What is false
100
what is the frequency of a pendulum with a period that is 10 seconds?
1/10 of a second
200
what are the four parts of a wave?
What is crest, trough, amplitude and wavelength
200
A wave that appears to stay in one place
What is a standing wave
200
why is it possible to get sunburn on a cloudy day
because ultraviolet rays also reflect from sand and water.
200
what beat frequency is produced by two tuning forks that vibrate simultaneously with frequencies 300 Hz and 311 Hz?
What is 11 Hz
300
True or false: The crests of a bow waves overlap at their edges
True
300
The sharp crack heard when the shock wave that sweeps behind a supersonic aircraft reaches the listeners
What is a Sonic Boom
300
a particle shadow
What is penumbra
300
True or false: Sound intensity is subjective
What is False
300
what is the wavelength of a kitchen microwave with a frequency of 2450 megahertz (2,45,000,000 Hz). (speed of light is 300000000 m/s)
.12 m or 12 cm
400
what type of interferences cause waves to go in-phase and out-of-phase?
in-phase: constructive out-of-phase: deconstructive
400
The phenomenon that occurs when the frequency of a vibration forced on an object matches the object's natural frequency and a dramatic increase in amplitude occurs
What is Resonance
400
the aligning of vibrations in a transverse wave, usually by filtering out waves of other direction.
What is polarization
400
A singer shattering a Crystal glass with her voice is a demonstration of
What is resonance
400
Radio waves are permitted to communicate on the "10-meter band". What frequency of radio waves corresponds to a wavelength of 10 m? (The speed of radio waves 3.0 x 10^8 m/s)
30,000,000 Hz
500
Why don"t we hear a sonic boom from a subsonic aircraft?
The sound wave's crest reaches our ears one at a time and are perceived as a continues tone.
500
A frequency at which an elastic object, once energized, will vibrate. minimum energy is required to continue vibration at that frequency.
What is natural frequency
500
Name all of the different waves that make up the electromagnetic spectrum.

500
Beats can be heard when two tuning forks..... a. are sounded together b. have almost the same frequency and are sounded together c. have the same frequency and are sounded tigether d. all of the above
b. have almost the same frequency and are sounded together
500
