C.2.2 Nature of wave propagation Key Definitions

Definition

Electromagnetic waves

Electromagnetic waves are composed of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of wave propagation.

Definition

Frequency

Frequency is the number of complete oscillations per unit time, measured in hertz (Hz).

Definition

Mechanical waves

Mechanical waves are waves that require a medium (such as air, water, or a solid) to propagate.
