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 points on a standing wave that have constructive interference?
What is an antinode?
200
The number of wave cycles that pass a point in one second
frequency
200
If a wave enters from one medium into another, name two factors that change about the wave.
(you must get BOTH correct)
What is velocity and wavelength.
200
An ambulance is driving away, and it is emitting a frequency of 900 Hz. Will the frequency that a stationary observer perceives increase, decrease, or remain the same?
What is decrease.
200
As a source of light is traveling toward an observer, what is the color shift seen?
What is blue shift?
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
