Which color has the highest frequency?
1 Answer
The color with the highest frequency in the visible light spectrum is **violet**.
To understand why, let’s break it down a bit more scientifically:
### The Electromagnetic Spectrum:
The visible light spectrum is part of the broader electromagnetic spectrum, which includes all types of electromagnetic radiation, from radio waves to gamma rays. Each type of radiation is characterized by its wavelength, which is the distance between two consecutive peaks (or troughs) of the wave. The frequency of the wave is the number of cycles (or wave crests) that pass a point in one second. The shorter the wavelength, the higher the frequency.
### Visible Light Spectrum:
Visible light is just a small portion of the electromagnetic spectrum, and it encompasses all the colors we can see, from red to violet. Each color in the visible spectrum has a different wavelength and frequency:
- **Red** light has the longest wavelength (around 620-750 nm) and the lowest frequency.
- **Violet** light has the shortest wavelength (around 380-450 nm) and the highest frequency.
Since **frequency** and **wavelength** are inversely related (higher frequency means shorter wavelength), violet light, being at the end of the visible spectrum, has the highest frequency.
### Breakdown of Visible Light Wavelengths:
Here is a more detailed list of visible colors and their typical wavelength ranges:
- **Red**: 620–750 nm (lowest frequency)
- **Orange**: 590–620 nm
- **Yellow**: 570–590 nm
- **Green**: 495–570 nm
- **Blue**: 450–495 nm
- **Indigo**: 425–450 nm
- **Violet**: 380–425 nm (highest frequency)
### Why does violet have the highest frequency?
The color violet corresponds to light with a wavelength in the shortest range of the visible spectrum. Because wavelength and frequency are inversely proportional, violet light's shorter wavelength means that its frequency is higher compared to other colors like red or blue. The electromagnetic wave frequency for violet light typically ranges from about **668 THz (terahertz)** to **789 THz**, which is the highest frequency for visible light.
In summary, **violet** has the highest frequency among the visible colors, and this is a result of its shorter wavelength.
