What is wavelength?
Amplitude
What is the height of the wave from its resting position to the crest or trough?
Our ears have different sensitivities to different frequencies
What is true?
Waves can transport energy but not ____
What is matter?
_________ waves have both longitudinal (p-waves) and transverse waves (s-waves) and surface waves
What are seismic waves?
The number of waves that pass a point in a certain amount of time
What is frequency?
A wave in which the particles move parallel to the direction of the wave
What is a longitudinal wave?
High pitch will always have high amplitude
What is False? (The wavelength will be close together but not necessarily the amplitude)

What is increases?
True or False: An example of a longitudinal wave are sound waves.
What is true.

What is the highest point of a wave?
A disturbance that transfers energy from one place to another without transferring matter
What is a wave?
Nodes are where a wave doesn't seem to be moving, like in the sand art where we see the patterns
What is True?
With reflection, the wave always changes _________.
What is direction.
What is higher amplitude?
A wave in which the particles move perpendicular to the direction of the wave
