Introduction to Wave Models (00:00 - 01:45)

Definition of a wave as a repeating pattern of motion.
The use of models to represent phenomena like sound and water.
Explanation of the 'medium' as the material through which a wave travels.

Anatomy of a Wave (01:45 - 03:20)

The resting position is defined as the state of the medium without a wave.
Identification of the crest (highest point) and the trough (lowest point).

Key Characteristics: Frequency and Wavelength (03:20 - 05:10)

Wavelength is the distance between identical points on consecutive waves.
Frequency is the number of waves that pass a point in a given time, measured in Hertz.
The relationship between frequency and the pitch of a sound.

Amplitude and Energy Relationships (05:10 - 07:00)

Amplitude is the distance from the resting position to a crest or trough.
Discussion on how amplitude relates to sound volume (loudness).
The mathematical relationship where energy is proportional to the square of the amplitude.

Predicting Energy Transfer (07:00 - 08:00)
