Why red colour light is used for danger signal
Answers
Explanation:
It is all about scattering effect of lights with different colours. Less the scattering causes greater distance of travelling the light. Less scattering is also helps the light to travel through fog, cloud, dust e.t.c.
The scattering of light is inversely proportional to the fourth power of the wavelenght of the light.
Red colour has bigger wavelength than any other colour. So the scattering of light is less for red light which leads to traveling of greater distance. Thats why red light is used for danger signal. So that it can be visible from far distance.
Answer:
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.
