Wave
answer
A disturbance that transfers energy through matter or space.
question
Crest
answer
Highest point of a wave
question
Trough
answer
Lowest point of a wave
question
Amplitude
answer
The height of a wave
question
What is the relationship between a wave's amplitude and the amount of energy it carries?
answer
as amplitude increases, the amount of energy carried by the wave increases(direct relationship).
question
Wavelength
answer
Horizontal distance between the crests or between the troughs.
question
What is the relationship between a wave's wavelength and the amount of energy it carries
answer
As wavelength increases, the amount of energy carried by the wave decreases(indirect relationship).
question
Frequency(units)
answer
The number of waves produced in a given.
-It is measured in hertz.
question
What is the relationship between a wave's frequency and the amount of energy it carries?
answer
As frequency increases, the amount of energy carried by the wave increases(direct relationship).
question
What is the relationship between a wave's frequency and its wavelength?
answer
As wavelength increases, frequency decreases(indirect relationship).
question
