Question #afab2

Answer 1

Violet light has the shortest wavelength.

Explanation:

Visible light has a wavelength range of about 400 nm to 750 nm.

The visible colours from shortest to longest wavelength are: violet, indigo, blue, cyan, green, yellow, orange, and red.

The spectrum is continuous and the colours merge into each other, so the cut-off ranges of the colours are somewhat arbitrary.
