Blue coloured light is not suitable to be used as danger signals. Write the reason
Answers
Answer:
Danger signals are red in color because it is scattered the least by air molecules. The effect of scattering is inversely related to the fourth power of the wavelength of a color. Since the color red has the highest wavelength of all the colors we can see it scattered the least. So, red light is used as a danger signal as it is able to travel the longest distance through the fog, rain, etc.
