Key Concepts

Wavelength

Wavelength is the distance between successive corresponding points of a wave, such as the distance between two consecutive crests or troughs. It is a key property of waves, determining many characteristics of their behavior, including how they interact with matter.

Wave Speed Equation

The wave speed equation, expressed as c = f × ?, relates the speed (c) of a wave to its frequency (f) and wavelength (?). For electromagnetic waves, the speed c is the speed of light in a vacuum (~3.0 × 10^8 m/s), which allows for the determination of frequency when the wavelength is known.

Frequency

Frequency refers to the number of complete wave cycles or oscillations that occur in one second, and it is measured in Hertz (Hz). It provides an indication of how rapidly the wave oscillates, and in the context of electromagnetic waves, higher frequencies correspond to shorter wavelengths and greater energy.
