Quick Reference

cSpeed of light (3×10⁸ m/s)

fFrequency (Hz)

λ (lambda)Wavelength (m)

Radio wavesLong wavelength, low frequency

Gamma raysShort wavelength, high frequency

Overview

Convert between different frequency units (Hz, kHz, MHz, GHz) and wavelength. Frequency and wavelength are inversely related for electromagnetic waves traveling at the speed of light.

💡

Pro Tips

1 kHz = 1,000 Hz, 1 MHz = 1,000,000 Hz, 1 GHz = 1,000,000,000 Hz
Wavelength λ = c / f, where c is the speed of light
Higher frequency = shorter wavelength, lower frequency = longer wavelength
Common frequency ranges: AM radio (535-1605 kHz), FM radio (88-108 MHz), WiFi (2.4 GHz)

Fun Facts

"The highest frequency radio waves are used for radar and satellite communications"
"ELF (Extremely Low Frequency) waves (3-30 Hz) can travel through seawater and ground"
"The frequency of your WiFi router is probably 2.4 GHz or 5 GHz"
"Lightning produces radio waves across a huge frequency spectrum"
"Some animals can detect frequencies humans cannot hear (ultrasound, infrasound)"

Formula: λ = c / f
