Red color is used for signals!!
Actually you have read that Red color have maximum wavelength and Blue color have minimum wavelength among all colors
Also sky appears red in morning and evening as the smaller wavelength blue color disperse most in the environment as it collides with small dust particles and atoms and molecules of atmosphere
Red color with longest wavelength is not dispersed too much as the small particles of the atmosphere are not sufficiently large to deviate the path of red color light waves
Same thing happens in day to day life !!!
Red color is not deviated too much from its path and hence do not disperse in the environment even when the atmosphere is not clear
Even in winters when all other colors with small wavelength are dispersed due to collision with smoke and dust particles in fog or smog, red color light is not dispersed and therefore work as symbols for vehicles and other things
Listen JANNAT JUBAIR se nafrat to krogi hi kyon ki wo ek to ldki hai tumhare hi jaisi pr tumse lakh guna jyada successful hai, or to or uske pichhe itne sare ldke diwane hai, to obviously tum usse nafrat krogi,nhi to usne tumhara kuchh bigada hai kya?? Nhi na !!!!!!
