Which color has the longest wavelength?

Answer 1

Of the colors in the visible spectrum, red has the lowest frequency and the longest wavelength. As you move on "up" the spectrum, wavelengths get shorter.

Red has the longest spectrum of all visible light. But infrared is even longer and there are many more "colors" but you can't see them.

Answer 2

The spectrum of visibly colored light is usually recalled by the name "Roy G Biv". This stands for the colors Red - Orange - Yellow - Green - Blue - Indigo - Violet. The wavelength of red light is the longest and the wavelength of violet light is the shortest. The visible light spectrum corresponds to about 700 nm (red light) to 400 nm (blue light).

Answer 3

You didn't list any choices, so we don't know which colors you want us to consider.

As the wavelength of visible light increases, the color changes in the direction of
the red end of the rainbow. Red is the color with the longest visible wavelength.
Blue is the color with the shortest.

Answer 4

As the wavelength of visible light increases, the color changes in the direction of
the red end of the rainbow. Red is the color with the longest visible wavelength.
Blue is the color with the shortest.

Answer 5

In visible light, the color RED has the longest wavelength and VIOLET has the shortest.

Answer 6

The longest wavelength is red. The next longest is orange, then yellow, green, blue, and finally - purple.

Answer 7

The longest electromagnetic wavelengths that

can be detected by the human eye appear red.

Answer 8

Please don't write "the following" if you don't provide a list.

Answer 9

The longest wavelength to which your eye responds is the wavelength

of the last color you can see on the RED end of the visible spectrum.

Answer 10
