This document discusses types of waves and wave parameters. It begins by outlining the objectives of identifying types of waves, differentiating between them, and identifying wave parameters and dependencies. It then defines waves and introduces two main types: mechanical and electromagnetic waves. Mechanical waves are further divided into longitudinal waves, where particle motion is parallel to the energy propagation, and transverse waves, where particle motion is perpendicular. Five key wave parameters - amplitude, period, frequency, wavelength, and wave speed - are defined and their relationships explored. Examples of different wave types are provided.

TYPES OF WAVES
Mechanical waves are waves created by the
disturbance of a material substance or medium
as a result of repeated periodic motion of the
particles of the medium. The energy is
propagated as a result of the motion of the
particles of the medium, but medium remains at
its previous position.
Mechanical waves are classified as:

LONGITUDINAL WAVES
• Longitudinal waves are a series of compressions
and rarefaction.
• A compression occurs where some of the wave
particles are moving toward a common point
where pressure and density it at its maximum.

are moving away from a common point where
pressure and density are at a minimum.
