This page details the frequencies and wavelengths associated with different colors in the visible light spectrum, namely Red, Orange, Yellow, Green, Blue, and Violet.

Introduction

The visible light spectrum is a small part of the broader electromagnetic spectrum that our eyes can perceive as color. Each color corresponds to a specific range of frequencies and wavelengths.

Here’s a table summarizing the approximate frequencies and wavelengths for each color:

ColorFrequency (THz)Wavelength (nm)
Red400-484620-750
Orange484-508590-620
Yellow508-526570-590
Green526-606495-570
Blue606-668450-495
