The wavelength range of visible light can vary slightly depending on the source you refer to or the context in which it is being discussed. However, the commonly accepted range for visible light is approximately 390 to 700 nanometers (nm).
Visible light is a small portion of the electromagnetic spectrum, which encompasses a wide range of wavelengths. The specific colors we perceive in visible light correspond to different wavelengths within this range. Here is a general breakdown of the colors and their corresponding approximate wavelengths:
- Red light: Around 620-750 nm
- Orange light: Around 590-620 nm
- Yellow light: Around 570-590 nm
- Green light: Around 495-570 nm
- Blue light: Around 450-495 nm
- Violet light: Around 380-450 nm
These values represent approximate ranges, and there can be some overlap or variation depending on the source you consult. Different sources may use slightly different boundaries for the colors or may consider different levels of sensitivity in human vision. That's why you may encounter some discrepancies in the exact values mentioned.
However, for most practical purposes, the range of 390-700 nm is commonly used as a general guideline to define the wavelengths of visible light.
