24 views

Red has the strongest wavelength among visible colors, ranging from approximately 620 to 750 nanometers. This makes it the longest wavelength in the visible spectrum, allowing it to penetrate further and be seen more clearly from a distance.

FAQs & Answers

  1. Why does red light have the longest wavelength? Red light has the longest wavelength among visible colors because its electromagnetic waves range from approximately 620 to 750 nanometers, making it lower in frequency and longer in wavelength compared to other visible colors.
  2. How does wavelength affect the visibility of colors? Longer wavelengths, like red, can penetrate further and appear more clearly from a distance, while shorter wavelengths such as blue tend to scatter more easily.
  3. What is the visible light spectrum? The visible light spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, with wavelengths ranging roughly from 380 to 750 nanometers.
