Why Is Red Significant as the First Colour in the Rainbow?
Red is significant as the first color in the rainbow because it has the longest wavelength of visible light. This position symbolizes strong emotions, such as love and passion, as well as being a prominent color in nature.
According to the National Geographic Society, the colors of the rainbow are produced by the dispersion of light through water droplets in the atmosphere, creating a spectrum of color.
The significance of red in the rainbow arises from its physical properties. Light travels in waves, and different colors correspond to different wavelengths. Red light has a wavelength of about 620 to 750 nanometers. This longer wavelength allows it to bend less during dispersion, placing it at one end of the visible spectrum.
Dispersion is the process where light separates into its component colors. When sunlight passes through raindrops, it bends, reflecting off the inside surface of the droplet. The light then exits, refracting again and forming a circular arc of color. The bending, or refraction, occurs at different angles for each wavelength, resulting in the rainbow’s color order with red on the outer edge.
Specific conditions like rainfall and sunlight create the opportunity for a rainbow to form. For example, a sunny day after a rainstorm can lead to ideal conditions for observing a rainbow. The sunlight must shine at a specific angle, usually low in the sky, for the light to refract properly and create the visible spectrum.
In summary, red’s position as the first color in the rainbow stems from its longer wavelength, which influences its ability to refract and remain prominent in light dispersion. Understanding these factors illuminates the beauty of this natural phenomenon.

How Does Light Create the Illusion of the Rainbow?
Light creates the illusion of a rainbow through a process called refraction, dispersion, and reflection. First, sunlight enters a raindrop in the atmosphere. As light enters the raindrop, it bends or refracts. Different colors of light bend at slightly different angles because they have different wavelengths. This bending separates the light into its component colors, creating a spectrum.
Next, the light reflects off the inside surface of the raindrop. This reflection helps to maintain the separation of the colors. After reflecting, the light exits the raindrop, bending again as it moves from the denser water back into the air. This final bending enhances the visibility of the separated colors in the form of a circular arc.
The combination of these steps results in the viewer seeing a rainbow. The specific order of the colors follows the sequence: red, orange, yellow, green, blue, indigo, and violet, commonly known as ROYGBIV. The overall effect occurs when sunlight shines on raindrops in the atmosphere during or after a rain shower, creating this beautiful optical phenomenon.
