Complete Guide to Frequency and Wavelength Conversion

Frequency is a fundamental physical quantity that measures the number of oscillations or cycles per unit time. Our comprehensive frequency wavelength converter helps you convert between all major frequency units including Hz, kHz, MHz, GHz, and THz, plus calculate corresponding wavelengths.

Understanding Frequency Units

  • Hz (Hertz): Base unit, 1 cycle per second
  • kHz (Kilohertz): 1,000 Hz = 10³ Hz
  • MHz (Megahertz): 1,000,000 Hz = 10⁶ Hz
  • GHz (Gigahertz): 1,000,000,000 Hz = 10⁹ Hz
  • THz (Terahertz): 1,000,000,000,000 Hz = 10¹² Hz

Frequency and Wavelength Relationship

Fundamental Formula:

λ = c / f

Where: λ = wavelength, c = speed of light (299,792,458 m/s), f = frequency

Common Frequency Applications

Audio Frequencies

  • 20 Hz - 20 kHz: Human hearing range
  • 440 Hz: Musical note A4
  • 20-200 Hz: Bass frequencies
  • 200-2000 Hz: Midrange
  • 2-20 kHz: Treble frequencies

Radio Frequencies

  • 88-108 MHz: FM radio
  • 535-1605 kHz: AM radio
  • 2.4 GHz: WiFi, Bluetooth
  • 5 GHz: WiFi, radar
  • 800-2600 MHz: Cellular

Electromagnetic Spectrum

Frequency Range Wavelength Type
3-30 Hz 100,000-10,000 km Extremely Low Frequency
3-30 kHz 100-10 km Very Low Frequency

Frequently Asked Questions

What is the relationship between frequency and wavelength?

Frequency and wavelength are inversely proportional. As frequency increases, wavelength decreases. The relationship is defined by λ = c/f, where c is the speed of light.

How do I convert MHz to GHz?

To convert MHz to GHz, divide by 1000. For example: 2400 MHz ÷ 1000 = 2.4 GHz.

What frequency range is used for WiFi?

WiFi primarily uses 2.4 GHz (2400-2485 MHz) and 5 GHz (5150-5850 MHz) frequency bands.
