A disturbance that transfers energy from place to place.
What is a wave.
100
This is the highest part of a transverse wave.
What is a crest or peak.
100
The type of wave that moves it's medium parallel to the direction in which the waves travel.
What is longitudinal.
100
The interaction between waves, it can either be constructive or destructive.
What is interference.
200
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.
What is a transverse wave.
200
The material (not too big, and not too small) through which a wave travels.
What is a medium.
200
(***MULTIPLY THE POINT VALUE BY 2!!!!!*****)
The speed of a wave is 50 m/s. What is the frequency AND period of the wave if the wavelength is 0.01 meter? (You need both to get the points)
What is f=5,000 Hz. T=1/5,000 OR 0.0002 seconds.
200
A wave passes a point three times in one second. This is its frequency.
What is 3 Hz.
200
Unit of measurement for frequency.
What is Hertz.
300
The part of a longitudinal wave where the particles of the medium are close together
What is compression.
300
The time it takes for one complete wave to pass a certain point.
What is the period.
300
The frequency of a wave is 10 Hz. This is its period. (INCLUDE correct units)
What is 1/10 seconds or 0.1 seconds.
300
(***MULTIPLY THIS POINT VALUE BY 2!!!!***)
This characteristic of a wave tells you how much energy it has.
What is the amplitude.
300
This is the reason that you cannot hear sound in outer space.
What is because sound waves are a longitudinal wave and they require a medium to travel (a solid, liquid or a gas).
400
The property of a wave that is directly related to energy. It is defined as the maximum distance that particles of the medium carrying the wave move away from their rest position.
What is amplitude.
400
The wavelength of a transverse wave is often measured from....
What is crest to crest OR trough to trough.
400
Waves with longer wavelengths have a ________ frequency and waves with shorter wavelengths have a ________ frequency. (Options are higher or lower)
What is 1. lower 2. higher
400
The number of complete waves that pass through a given point in a certain amount of time.
What is frequency.
400
A competitive jumproper can spin the rope around 4.2 times in one second. What is the frequency of the rope? The period? (Need BOTH correct answers to get points)
What is frequency = 4.2 Hz // Period - 1/4.2 seconds OR 0.238 seconds.
500
The part of a longitudinal wave where the particles of the medium are far apart.
What is rarefaction.
500
(****MULTIPLY THE POINT VALUE BY 2!!!!****)
The frequency of 300 waves that pass a point in one minute?
What is 5 Hz.
500
The speed of sound in air is about 340 m/s. What is the wavelength of sound waves produced by a guitar string vibrating at 490 Hz?
What is 0.69 m
500
A certain musician can vibrate her vocal chords at 900 Hz. If the speed of sound in air is 340 m/s, what is the wavelength of the sound produced?
What is 2.65 meters
500
(****MULTIPLY THIS POINT VALUE BY 1/5th!!!!!****)
The distance between two corresponding parts of a wave, measured either from crest to crest or trough to trough in transverse waves, or from compression to compression in longitudinal waves.
