Visible Light Spectrum
The visible light spectrum is a tiny portion of the electromagnetic spectrum that our eyes can perceive. It's often visualized as a rainbow, with colors ranging from red to violet. Each color corresponds to a specific range of wavelengths:
* Red: Longest wavelengths (approximately 700-635 nanometers)
* Orange: (approximately 635-590 nanometers)
* Yellow: (approximately 590-560 nanometers)
* Green: (approximately 560-520 nanometers)
* Blue: (approximately 520-490 nanometers)
* Indigo: (approximately 490-450 nanometers)
* Violet: Shortest wavelengths (approximately 450-400 nanometers)
Beyond Visible Light
It's important to note that the electromagnetic spectrum extends far beyond visible light. Here's a glimpse of what's beyond the rainbow:
* Infrared (IR): Longer wavelengths than red, associated with heat.
* Microwaves: Even longer wavelengths used in communication and cooking.
* Radio waves: Longest wavelengths, used for broadcasting and communication.
* Ultraviolet (UV): Shorter wavelengths than violet, associated with sunburns and tanning.
* X-rays: Even shorter wavelengths, used in medical imaging.
* Gamma rays: Shortest wavelengths, highly energetic and used in cancer treatment.
