W
What is a wave?
An energy source
What do all waves have?
A back-and-forth or up-and-down movement of an object.
What is a vibration?
Solids, liquids, and gases, but not a vacuum.
What can mechanical waves travel through?
What is the material through which a wave travels?
What is in a transverse wave, the disturbance moves this way?
A flag waving in the breeze.
Parallel to the direction the wave travels.
What is in longitudinal waves, this is the way particles move?
Longitudinal waves can travel only through matter.
What are sound waves?
What how are water waves formed?
In circles.
What is the water particles in water move this way?
The maximum distance the wave moves from its rest position.
What is the amplitude of a wave?
Four times greater
The distance between one point on a wave to the same point on the next wave.
What is a wavelength?
Hertz (Hz)
What is how frequency is measured?
The number of times a wave pattern repeats in a given time.
What is a frequency?
The perception of how high or low a sound seems.
What is a pitch?
A higher pitch
Higher than 20,000 Hz
What is the frequency that is called ultrasound?
The bouncing of a wave off a surface.
What is reflection?
Energy from a wave is transferred to the medium it travels through.
What is when absorption occur?
Solids
What does sound travel fastest through?
Faster
What happens as the temperature increases in gases, then sound waves travel this way?
The change in direction of a wave when it travels by an edge or through an opening.
What is diffraction?
The object or opening becomes similar in size to the wavelength.
What is when more diffraction occurs?
