Frequency & Wavelength Converter

About This Tool

This converter is a fundamental tool for physics, electronics, and telecommunications, handling conversions for frequency and its inverse relationship with electromagnetic wavelength. The base unit for frequency is the hertz (Hz), which represents one cycle per second.

Frequency and wavelength are inversely proportional, linked by the speed of light (c ≈ 299,792,458 m/s). This tool can convert between different orders of frequency (like kHz, MHz, GHz) and also calculate the wavelength in a vacuum for a given frequency, and vice-versa. This is essential for understanding everything from radio waves to visible light and gamma rays.

Tips & Features

• The Core Relationship: The fundamental formula is Wavelength (λ) = Speed of Light (c) / Frequency (f). This tool uses this formula for conversions between frequency and wavelength units.
• Frequency Units: These measure the number of oscillations or cycles per second. They are used to describe radio signals (MHz), computer processor speeds (GHz), and sound waves (Hz, kHz).
• Wavelength Units: These measure the spatial period of a wave—the distance over which the wave's shape repeats. Wavelength determines the color of visible light (in nanometers) and the antenna size needed for radio communication.
