Wave Basics
Wave Speed
Wave Interference
Light and Sound
Wave Boundaries and Standing Waves
100
The distance between two consecutive crests of a wave.
wavelength
100
the product of wavelength and frequency
What is wave speed
100
When two waves meet and add together, its called this.
constructive interference
100
Sound is this type of wave
longitudinal
100
What are the high energy points on a wave referred to as?
Crests
200
The number of wave cycles that pass a point in one second
frequency
200
If a wave has a frequency of 10 Hz and a wavelength of 2 m, its speed is this?
What is 20 m/s
200
When two waves superimpose each other out of phase
Destructive interference
200
These type of waves have the lowest frequency on the Electromagnetic Spectrum.
radio waves
200
This harmonic frequency is shown in the standing wave below.
3rd
300
This is the height of a wave from resting position to the crest.
amplitude
300
If speed stays the same and the frequency increases, what must happen to the wavelength?
decreases
300
The bending of waves as they pass from one medium to another.
refraction
300
The portion of the Electromagnetic Spectrum responsible for suntans or sunburns.
UV light
300
If the wavelength of the 1st harmonic is 6 m, what is the wavelength of the 2nd harmonic?
3 m
400
This is a waves where the particles vibrate parallel to the direction of the wave
What is longitudinal wave
400
Electromagnetic waves travel at this speed?
What is 3.0 x 10^8 m/s
400
The apparent change in frequency of a wave due to motion of the source of the sound in relation to the observer.
The Doppler Effect
400
Electromagnetic waves differ from mechanical waves in that they don't require this to travel through.
a medium
400
The points on the standing wave that remain stationary.
Nodes
500
This is a wave where the particles vibrate perpendicular to the direction of the wave
What is a transverse wave
500
If the speed of a wave is 340 m/s and the period is 0.01 s, what is the wavelength?
3.4 meters
500
A pattern formed by overlapping waves in opposite directions.
standing wave
500
A term for the reflection of sound waves
an echo
500
If the length of the string is 4m, what is the wavelength?
2 m
