Which Visible Color Has the Longest Wavelength?
การแนะนำ: 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.
ฉัน. 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 (นาโนเมตร). The longer the wavelength, the lower the energy of the light.
ครั้งที่สอง. Exploring the Visible Colors
1. Red (Approximately 620-750 นาโนเมตร)
Red is the color with the longest wavelength within the visible spectrum. It has a wavelength range of approximately 620-750 นาโนเมตร. Red light has the least amount of energy among all the visible colors.
2. Orange (Approximately 590-620 นาโนเมตร)
Orange is the next color in the visible spectrum. It has a wavelength range of approximately 590-620 นาโนเมตร. Orange light possesses slightly higher energy than red light but lower energy than the subsequent colors.
3. Yellow (Approximately 570-590 นาโนเมตร)
Yellow comes after orange in the visible spectrum. It has a wavelength range of approximately 570-590 นาโนเมตร. Yellow light has a higher energy level compared to both red and orange light.
4. Green (Approximately 495-570 นาโนเมตร)
Green follows yellow in the visible spectrum and has a wavelength range of approximately 495-570 นาโนเมตร. It has a higher energy level than red, orange, and yellow light.
5. Blue (Approximately 450-495 นาโนเมตร)
Blue is the color with a shorter wavelength than green. It lies within the range of approximately 450-495 นาโนเมตร. Blue light has a higher energy level compared to red, orange, yellow, and green light.
6. Violet (Approximately 380-450 นาโนเมตร)
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 นาโนเมตร. Violet light possesses the highest energy level within the visible spectrum.
สาม. บทสรุป: The Longest Wavelength within the Visible Spectrum
Among the visible colors, red has the longest wavelength, ranging from approximately 620-750 นาโนเมตร. 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 นาโนเมตร, and possesses the highest energy level.
