Waves 1 Flashcards
What’s amplitude?
The distance each wave goes up or down from the starting point
As the energy of a wave increases…
The amplitude increases.
What’s the trough?
The lowest point of the wave
What’s frequency?
How many waves in each amount of time (seconds)
If you start shaking a slinky side to side FASTER, what will change?
Increase frequency AND decrease wavelength.
T/F: A wave transfers matter (particles) from one place to another
False
If you start shaking the slinky FARTHER from side to side, what will change? (not changing speed)
Increase the amplitude
T/F: A wave transfers energy from one place to another
True
As the amplitude of the wave increases, which of the following is true? (Wavelength increases, decreases, or frequency increases)
None of these are true.
What is the crest?
The highest point of the wave
As the frequency of the wave increases…
Its wavelength decreases
What’s wavelength?
The distance between crests.
What happens when there’s higher frequency?
Shorter wavelength
What happens when there’s lower frequency?
Longer wavelength
How is frequency measured?
Hertz (Hz)
