Why are fire trucks painted red?
Sunlight is composed of seven colors: red, orange, yellow, green, cyan, blue, and purple, and their wavelengths and deflection angles are different.
When sunlight shines on an object, various objects have different absorption and reflection abilities to light of different wavelengths, and various colors are formed.
Among visible light, red light has the longest light wave and the smallest deflection angle, which makes it easy to pass through water, raindrops, dust and fog. Orange and yellow light are not afraid of obstruction and can penetrate the above objects. Therefore, the fire truck is painted red to allow people to see it from afar in foggy weather, dusty environment, or in heavy storms, and make way for it so that it can complete the firefighting and rescue mission as soon as possible.
