Amplitude: The distance from the mid-point of a wave to the crest (or trough) of a wave. Measured in meters.
Wavelength: The distance from the top of one crest to the next. Measured in meters.
Frequency: How often vibration occurs. Measured in Hertz.
Period: The time required to complete a cycle. Measured in seconds.
Wave: "A wiggle in space and time."
Constructive Interference: Interference caused when the crest of one wave overlaps with that of another wave. The product is reinforcement of the wave.
Destructive Interference: Interference caused when the crest of one wave overlaps with the trough of another. The product of this is cancellation of the wave.

Types of Waves:
- Transverse Waves: A wave in which the medium is at right angles to the direction in which the wave travels. Example: Electromagnetic Waves
- Longitudinal (Compression) Waves: A wave in which the particles of the medium move back in forth in the same direction of the wave. Example: Sound Waves
