The Electromagnetic & Acoustic Frequency Spectrum
Frequency defines fundamental oscillatory behaviors across physics, from sub-audible ocean acoustics to high-energy gamma radiation.
The Electromagnetic Spectrum at a Glance
- Audio Band (20 Hz – 20 kHz): Human hearing range, hi-fi sound reproduction, and musical instruments.
- AM Radio (530 kHz – 1,700 kHz): Medium wave ground-wave propagation.
- FM Radio & Aviation (88 MHz – 137 MHz): Very High Frequency (VHF) line-of-sight broadcasting.
- Cellular & Wi-Fi (700 MHz – 6 GHz): LTE/5G sub-6 GHz, Bluetooth (2.4 GHz), Wi-Fi 6E/7 (2.4 GHz, 5 GHz, 6 GHz).
- Millimeter Wave (24 GHz – 100 GHz): High-throughput 5G mmWave, automotive radar collision avoidance (77 GHz).
- Visible Light (400 THz – 790 THz): Optical wavelengths between 380 nm (violet) and 750 nm (red).
How to Use This Calculator
Enter your Frequency / Rotational Speed (e.g. 2.4), Frequency Unit — choose from Hertz (Hz, cycles/sec), Kilohertz (kHz, 10³ Hz), Megahertz (MHz, 10⁶ Hz), and Wave Propagation Velocity (Wavelength Calculation) — choose from Electromagnetic Waves in Vacuum / Air (c ≈ 3.0 × 10⁸ m/s), Fiber Optic Cable (v ≈ 2.0 × 10⁸ m/s, n=1.5), Coaxial / Copper Cable (v ≈ 2.3 × 10⁸ m/s, VF=0.77). Results update instantly as you type — adjust any value to compare scenarios.
The Formula
Frequency (f) is the rate of recurring events per unit time:1 Hz = 1 cycle per second = 1 s^-1 conversions and physical relationships:- Period (T): T = (1) / (f)- Angular Frequency (ω): ω = 2π f (rad/s)- Rotational Velocity: RPM = f × 60- Wavelength (λ): λ = (v) / (f), where v is propagation velocity (c = 299,792,458 m/s for light in vacuum).
Worked Example
For example, a Wi-Fi frequency of 2.4 GHz: . The cycle period is the angular frequency is and the free-space wavelength is .
Understanding Your Result
Unit conversions are exact by definition within a given measurement system (e.g., 1 km = exactly 1,000 m). Cross-system conversions (metric to imperial) use defined exchange factors: 1 inch = exactly 2.54 cm; 1 pound = 0.45359237 kg. Round your converted result to match the precision of your original measurement — expressing more decimal places than your input justifies implies false accuracy. For regulatory, legal, or safety-critical applications, verify which measurement system is required by the applicable standard.
