Which Visible Color Has the Longest Wavelength?
Introduction: The Visible Spectrum and Wavelengths
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. It consists of various colors, ranging from red to violet. Each color within the spectrum has a specific wavelength associated with it. In this article, we will explore the visible colors and determine which one has the longest wavelength.
I. What is Wavelength?
Wavelength is the distance between two consecutive peaks or troughs of a wave. In the context of visible light, wavelength is often measured in nanometers (nm). The longer the wavelength, the lower the energy of the light.
II. Exploring the Visible Colors
1. Red (Approximately 620-750 nm)
Red is the color with the longest wavelength within the visible spectrum. It has a wavelength range of approximately 620-750 nm. Red light has the least amount of energy among all the visible colors.
2. Orange (Approximately 590-620 nm)
Orange is the next color in the visible spectrum. It has a wavelength range of approximately 590-620 nm. Orange light possesses slightly higher energy than red light but lower energy than the subsequent colors.
3. Yellow (Approximately 570-590 nm)
Yellow comes after orange in the visible spectrum. It has a wavelength range of approximately 570-590 nm. Yellow light has a higher energy level compared to both red and orange light.
4. Green (Approximately 495-570 nm)
Green follows yellow in the visible spectrum and has a wavelength range of approximately 495-570 nm. It has a higher energy level than red, orange, and yellow light.
5. Blue (Approximately 450-495 nm)
Blue is the color with a shorter wavelength than green. It lies within the range of approximately 450-495 nm. Blue light has a higher energy level compared to red, orange, yellow, and green light.
6. Violet (Approximately 380-450 nm)
Violet is the color at the end of the visible spectrum. It has the shortest wavelength among all the visible colors, ranging from approximately 380-450 nm. Violet light possesses the highest energy level within the visible spectrum.
III. Conclusion: The Longest Wavelength within the Visible Spectrum
Among the visible colors, red has the longest wavelength, ranging from approximately 620-750 nm. It has the least amount of energy compared to the other colors. On the other hand, violet has the shortest wavelength, ranging from approximately 380-450 nm, and possesses the highest energy level.
