Which colors has a wavelength shorter than the others?

blue, indigo and violet

Explanation: looking at the visible light spectrum, we have

R O Y G B I V

Where R = red , O = orange light, Y = yellow, G = green, B = blue, I = indigo and V = violet.

Towards the right of the spectrum is increasing frequency and energy which implies that red light has the least energy and frequency and violet has the highest energy and frequency.

Also along from left to right of spectrum is decreasing wavelength.

Hence red light has the highest lomgestvand violet has the shortest wavelength.

So we can conclude that the shades of blue that's blue, indigo and violet has the least wavelength.
