Light is indeed a form of electromagnetic radiation. Electromagnetic radiation encompasses a whole spectrum of energy waves, and visible light is just a small portion of that spectrum. It's the part of the spectrum that our eyes can detect and perceive as different colors.
Electromagnetic radiation travels in waves and carries energy. The key difference between various types of electromagnetic radiation lies in their wavelength. Here's a breakdown:
- Electromagnetic Spectrum: This spectrum includes radio waves (longest wavelength), microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays (shortest wavelength).
- Visible Light: Visible light occupies a tiny portion of the spectrum with wavelengths ranging from about 400 nanometers (violet) to 700 nanometers (red). These different wavelengths are what our brains perceive as distinct colors.
So, next time you look at the sun or a light bulb, remember you're experiencing a tiny sliver of the vast electromagnetic spectrum!
