Which Color Of Rainbow Has Longest Wavelength. The visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow. We see the waves as the colors of the rainbow.
Red is the color on the visible electromagnetic spectrum that has the longest wavelength. Red has the longest wavelength the shortest frequency and the lowest energy. Each color has a different wavelength.
Red Red is the color at the top of the rainbow it has the longest wavelength.
These colors are red orange yellow green blue indigo and violet. Red has the longest wavelength of visible light about 650 nanometer s. For example red light has the longest wavelength and only bends at about a 42-degree angle. Violet light in contrast has the shortest wavelength and bends at around 40 degrees before exiting the water droplet.
