Why is denger signallights red in colour

Answer 1

Ello user !!!!!!

Here is your answer,

====================================================

The primary reason why the color red is used for danger signals is that red light is scattered the least by air molecules.

The effect of scattering is inversely related to the fourth power of the wavelength of a color.

So red light is able to travel the longest distance through fog, rain, and the alike.

HOPE THIS HELPS YOUU :)

As the colour RED scatters minimum so it would be easy to notice it from a distance. It would also be easy to see it in fog or dense mist.
