Study Notes
Speed of Light
- The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s) or about 186,282 miles per second (mi/s).
Electromagnetic Spectrum and Human Vision
- The human eye can detect light within the wavelength range of approximately 380 nanometers (nm) to 750 nanometers (nm).
Highest Speed in Nature
- The highest speed attainable in nature is the speed of light, which cannot be exceeded by any object with mass.
Intuitive Notion of Light Travel
- The intuitive notion about the travel of light is that it is instantaneous, allowing us to perceive events as they happen, despite that light takes time to travel over distances.
Wavelength Range of Light
- The wavelength range of light spans from about 1 millimeter (mm) for infrared radiation to 10 picometers (pm) for gamma rays, with visible light fitting into the 380-750 nm range.
