You've probably seen it many times before. You may have traveled in it. You may have noticed that whatever the school bus is, their color is always yellow. One wonders why all school buses are yellow.
One thing to keep in mind is that the color of the school bus is not just a matter of choice. So there is a scientific reason for this. Each color has its own wavelength and frequency. This means we use red as a stop light for traffic signals.
A red wavelength is about 650 nm. At the same time red color does not spread. As such, this red light is clearly visible even in daylight. That is why it is also used to indicate danger. The same goes for using yellow for school buses.
The VIBGYOR of colors is a set of seven colors. These include purple, sky blue, green, yellow, orange, and red. In the case of wavelengths, the yellow color falls below the red color. This means that the wavelength of yellow is less than that of red. However, more than blue.
Now red was already used to indicate danger. The best color was yellow, which could be used for school bus. Another specialty of yellow is. The yellow color is clearly visible in rain, fog and darkness.
Lateral peripheral vision means that one can easily see in the corner or around. That is, if one does not look straight ahead, he will see a yellow bus approaching. As the color of the school bus is yellow, the chances of accidents on the highway are less.
In India, the Supreme Court has issued various guidelines for school buses. Including yellow. If there is a school cab, there should be a green stripe of 150 mm along with the yellow color. The green stripe should be on all four sides of the cab.
