“What are two differences between the red and green electromagnetic waves in a rainbow? ”

In a rainbow, red and green are two different colors representing different wavelengths of electromagnetic waves. Here are two key differences between red and green electromagnetic waves in a rainbow:

1. Wavelength: The most fundamental difference is the wavelength of the waves. Red light has a longer wavelength compared to green light. In the electromagnetic spectrum, longer wavelengths correspond to colors like red, while shorter wavelengths correspond to colors like green.
2. Perceived Color: The perception of color is another difference. Red and green are at opposite ends of the visible spectrum, and they are perceived as distinct colors by the human eye. Red light is associated with longer wavelengths, and green light is associated with intermediate wavelengths. These differences in wavelength lead to differences in the color that we perceive.

Remember that a rainbow is a spectrum of colors, each corresponding to a different wavelength of light. Red and green are just two specific colors within this spectrum, and they differ in terms of their wavelength and perceived color.
