Properties of visible radiation include:
1. **Wavelength Range:** Visible radiation falls within the wavelength range of approximately 400 to 700 nanometers, making it visible to the human eye.
2. **Color Perception:** Different wavelengths of visible light correspond to different colors that we perceive, such as red, orange, yellow, green, blue, indigo, and violet (ROYGBIV).
3. **Reflection and Refraction:** Visible light can be reflected off surfaces, allowing us to see objects, and it can be refracted (bent) when passing through different mediums like air, water, or glass.
4. **Speed:** In a vacuum, visible light travels at a speed of about 186,282 miles per second (299,792 kilometers per second), making it the fastest form of electromagnetic radiation.
Understanding these properties helps us comprehend how visible light behaves and how we perceive the world around us based on the colors and interactions of light.
