What color of light has the shortest wavelength

Violet

Explanation:

Electromagnetic waves consists of oscillating electric and magnetic fields that vibrate in a direction perpendicular to the direction of propagation of the wave (for this reason, these waves are also called transverse waves).

Electromagnetic waves are generally invisible to human eye, apart from a very small portion of it, called visible light.

Waves in the visible part of the spectrum appear to us as a different color, depending on their wavelength. From shortest to longest wavelength, we have:

Violet (380-450 nm)

Blue (450-495 nm)

Green (495-570 nm)

Yellow (570-590 nm)

Orange (590-620 nm)

Red (620-750 nm)

So we see that violet is the color with shortest wavelength.
