What are the different components of the visible light spectrum?

The visible light spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye. It includes all the colors that make up white light, each corresponding to a specific wavelength range between approximately 400 to 700 nanometers (nm).

Components of the Visible Light Spectrum:

1. Violet
   • Wavelength: ~380–450 nm
   • Frequency: Highest in the visible range
   • Energy: Most energetic visible light
2. Blue
   • Wavelength: ~450–495 nm
   • Cool and calming color; often used in technology screens
3. Green
   • Wavelength: ~495–570 nm
   • Most sensitive color to the human eye
4. Yellow
   • Wavelength: ~570–590 nm
   • Bright and easily noticeable; often used in warning signs
5. Orange
   • Wavelength: ~590–620 nm
   • Warm and attention-grabbing
6. Red
   • Wavelength: ~620–700 nm
   • Frequency: Lowest in the visible range
   • Energy: Least energetic visible light
