Explanation:
In traffic signals red colour light is used to stop vehicles because it has the highest wave length.
The main reason the colour red is used for signals is that air molecules disperse red light the least. The impact of scattering is inversely linked to the fourth power of the wavelength of the colour.
As we move to the right of the VIBGYOR, the wavelength tends to raise, and since red is the last colour in vibgyor, it has the highest wavelength that can be seen from farther distances, which makes it convenient for the vehicles.
