Rewrite the jumbled paragraphs into a sequential text. Read the text in turns.

Although red color catches the most attention, it has already been attributed to danger so the next most attentive color-which can be distinguished in the crowd, yellow-is painted on the school bus.

We have always seen school buses painted yellow, but have you ever imagined why these buses are yellow?

The yellow color lies below the red color and has lower wavelength than the red but higher than the blue.

Colors play a major role in a day-to-day life. The wavelength and frequency of a color define its characteristics and use in the human life. For instance, why red is used for danger or stop signal in the traffic light, why the sky looks blue, and why school buses are painted yellow.

Even if a person is not looking straight, he can spot the yellow colored school bus in front of him.
That's why the school bus is painted yellow to lessen the possibility of an accident for the bus filled with children on the highway.

Red color has the maximum wavelength (approximately 650 nm) among the various components of the white light. It does not scatter like the blue color (which has relatively lower wavelength, and thus disperses the maximum and gives a blue color to the sky), and so is used to indicate danger and stop signal as it can be spotted from far away.

The color can also be spotted even in the rain, fog, and dew. Since the lateral peripheral vision of yellow is 1.24 times greater than the red color, it is more visible than the red itself.
