🌊 Wavelength — Physics Overview
Wavelength (λ) is the distance between successive wave crests (or troughs). It is the spatial period of a wave. For any wave, frequency (f) and wavelength (λ) are linked by wave speed (v): v = f × λ.
Key fact: For electromagnetic waves in vacuum, wave speed = c ≈ 2.998 × 10⁸ m/s. For sound in air at 20°C, v ≈ 343 m/s.
📐 Core Formulas
Wavelength: λ = v ÷ f — Meters (m)
Frequency: f = v ÷ λ — Hertz (Hz)
Wave Speed: v = f × λ — m/s
Period: T = λ ÷ v = 1 ÷ f — Seconds (s)
Photon Wavelength: λ = c ÷ f — uses speed of light c
De Broglie: λ = h ÷ (m × v) — Quantum wavelength of a particle
📏 Wavelength Reference by Spectrum
Radio waves: λ > 1 mm (up to hundreds of km)
Microwave: λ = 1 mm – 1 m
Infrared: λ = 700 nm – 1 mm
Visible light: λ = 380 – 700 nm
Ultraviolet: λ = 10 – 380 nm
X-rays: λ = 0.01 – 10 nm
Gamma rays: λ < 0.01 nm
🌍 Real-World Examples
Middle C (261.6 Hz, sound): λ = 343 ÷ 261.6 ≈ 1.31 m
Green light (550 nm): f = 3×10⁸ ÷ 550×10⁻⁹ ≈ 5.45 × 10¹⁴ Hz
WiFi 2.4 GHz: λ = 3×10⁸ ÷ 2.4×10⁹ ≈ 12.5 cm
Electron at 1 m/s (De Broglie): λ = 6.626×10⁻³⁴ ÷ (9.109×10⁻³¹ × 1) ≈ 727 nm
⚠️ Note: Wave speed depends on the medium. Always use the correct medium speed for accurate results.
