the amplitude of a wave is the same from the crest to the equilibrium position
true
the number of waves per second that pass by a given point is space is otherwise known as...
frequency
the reason for this purple peak being different in that...
wave heights add up to biggest number between red peak and blue peak
Image: the reason for this purple peak being different in that...
when two waves have slightly different wavelengths, they can form alternating regions of constructive interference and destructive interference
traffic police employ this phenomenon, known as _____ in order to _________
beats; measure speed of cars
which distance measures a full wavelength for one of the waves?
distance from C1 to C2
the timing and spacing of the waves is such that in 4 seconds, crest U1 and crest C2 will BOTH reach the point where crest C1 is now, in the diagram
what is the period of the C wave?
C wave's period is 4 sec
what will happen to the water when crests U1 and C2 interact?
constructive interference, yielding a crest taller than either U1 or C2
match the eave behaviors to the various interaction states

- forty feet deep
- happens after crest U interacts with rest J
- a moment of flat water
- forty foot tall "rouge wave"
- trough K interacts with trough M
- crest U interacts with trough M
- crest U interacts with trough M
- crest U interacts with trough J
Chuck Norris sings a good, even A note in the shower, at a frequency of 110 Hz with a wavelength of 3.14 m. His upstairs neighbor complains all the time how he can hear his loud singing. What is the speed of sound of Chuck's lovely singing voice.
(3.14m)(110Hz)= 345.4 m/s
You are designing an antenna for a radio that must pick up WGAX, all calculations/all the time, at frequency 100 MHz.
A good antenna must be designed with the transmitted signal's wavelength in mind. So....
What is the wavelength of this FM station?
300/100= 3
