Theory & Formulas
Waves are characterized by several fundamental properties, including wavelength, frequency, and speed. These properties are interrelated.
- Wavelength (λ - Lambda): This is the spatial period of the wave, the distance over which the wave's shape repeats. It's typically measured in meters (m) or its sub-multiples (cm, mm, µm, nm).
- Frequency (f or ν - Nu): This is the number of occurrences of a repeating event per unit of time. For waves, it's the number of crests (or troughs) passing a point per second. It's measured in Hertz (Hz), which is equivalent to cycles per second (s⁻¹).
- Wave Speed (v): This is the speed at which the wave propagates through a medium or vacuum. It's measured in meters per second (m/s). For electromagnetic waves (like light or radio waves) in a vacuum, this speed is constant and known as the speed of light, denoted by 'c' (approximately 299,792,458 m/s).
The fundamental relationship between these three quantities is:
Wave Speed (v) = Frequency (f) × Wavelength (λ)
From this, we can derive formulas to calculate any one quantity if the other two are known:
- To find Wavelength: λ = v / f
- To find Frequency: f = v / λ
- To find Wave Speed: v = f × λ
