Amplitude
What does amplitude measure?
The height of the wave from rest to crest (or rest to trough).
What is frequency measured in?
Hertz (hZ)
What is wavelength?
The distance between two corresponding parts of a wave (like crest to crest or trough to trough)
What direction do particles move in a transverse wave?
Up and down, at right angles to the direction the wave travels.
What direction do particles move in a longitudinal wave?
Back and forth (parallel to the direction the wave travels).
What does amplitude tell you about a wave’s energy?
Greater amplitude = more energy
If a wave makes 10 vibrations in 2 seconds, what is its frequency?
5hZ
A wave with a longer wavelength has what kind of frequency?
low
Give one example of a transverse wave.
Light, ocean waves, or electromagnetic waves.
Give one example of a longitudinal wave.
Sound wave
Does a higher amplitude= higher frequency?
No higher amplitude does not mean higher frequency.
What happens to the frequency when the wavelength increases?
it decreases
On a diagram, what would happen to the wave if the wavelength gets shorter?
More waves would fit in the same space (higher frequency).
What is the highest point of a transverse wave called?
crest
What is the area where particles are close together called?
Compression
Why does a wave with a larger amplitude cause more damage during an earthquake?
Because greater amplitude means more energy
Wave A= 1786 waves per second Wave B= 555 waves per second which wave has the longer wavelength?
Wave B
How is wavelength measured on a transverse wave?
From crest to crest or trough to trough
What is the lowest point of a transverse wave called?
trough
What is the area where particles are far apart called?
rarefaction
Two sound waves have the same frequency, but one sounds louder. What does this tell you about their amplitudes?
The louder sound has a greater amplitude, meaning it carries more energy.
How does frequency affect the energy of a wave?
higher frequency= higher energy
Wavelength for a longitudinal wave is measured how?
From compression to compression or rarefaction to rarefaction
at what angle does energy and the wave move in a transverse wave
right angle
In a longitudinal wave, what happens to the particles of the medium during a compression?
The particles move closer together,
