When the traffic lights turn red, we will stop driving a car or crossing a street. Why is red used for traffic lights instead of other colors?
As we know, scattering(散射)happens when light goes through the air. For the same media(媒介), if the wavelength is long, the scattering will be short. If the wavelength is short, the scattering will be long.
Of all lights we can see red has the longest wavelength, so the scattering is the weakest. That means the red travels far. In fact, it travels faster on rainy days.
Using the red light can help drivers in farther areas see the lights. It helps drivers slow down or stop in time. If drivers don’t see the red light until they are close, they may not be able to stop the car in time. An accident may happen. Red can also excite people. We can act more quickly when we see the color red. In a word, red lights help drivers stop in time and help prevent accidents.

A.red
