Reds, Oranges, Yellows: Which has a Longer Wavelength?
When it comes to light, the colors we see are determined by their wavelength. The shorter the wavelength, the higher the energy of the light, and the longer the wavelength, the lower the energy.
Out of all the visible colors, red has the longest wavelength, followed by orange, yellow, green, blue, indigo, and violet. This means that red light has the lowest energy, while violet light has the highest energy.
Visible Light Wavelengths
| Color | Wavelength (nm) |
|---|---|
| Red | 620-750 |
| Orange | 590-620 |
| Yellow | 570-590 |
| Green | 495-570 |
| Blue | 450-495 |
| Indigo | 420-450 |
| Violet | 380-420 |
