Vocabulary
A disturbance that transfers energy from one place to another is called _____________.
Wave
The highest part of a wave is called _________.
The Crest
A wave in which matter in the medium moves back and forth along the same direction that the wave travels.
Longitudinal Wave
What is a medium?
A material in which waves travel through.
The number of waves that pass a given point in a certain amount of time.
Frequency
The material in which waves travels through is called ________.
Medium
The lowest part of a wave is called _________.
The Trough
A wave in which the particles in the medium move back and forth at right angles to the direction that the wave travels.
Transverse Wave
Which medium (solid, liquid, or gas) does waves travel through the fastest?
Solid
A repeated back-and-forth or up-and-down motion.
Vibration
The _________ determines how long a wave is.
Wavelength
A measure of the size of the disturbance from a wave.
The Amplitude.
Waves that can travel only through matter, such as sound waves.
Mechanical Waves
