Oscillation caused by a disturbance; as it propagates through a medium (mechanical waves) or a vacuum (electromagnetic waves), it carries energy.
Horizontal line around which the wave oscillates, carrying energy.
Distance between two consecutive crests or troughs; it corresponds to the distance traveled by the wave over time (its period).
Gap in relation to the mean position.
Highest point of the wave.
Lowest point of the wave.
Maximum displacement of a wave in relation to its mean position; it corresponds to the amount of energy transmitted.
Motion of a wave leaving its source.
