We all know who Benjamin Franklin was. He was a very famous American statesman. He was also the first man to discover electricity. Franklin liked to study and to learn about new things. One day he heard from a friend that something black in colour holds the heat better than something white in colour. Franklin wanted to find out if this was true or not.
There was snow on the ground at the time. So he put two large pieces of cloth over the snow. One piece of cloth was black in colour, the other piece was white. Then he waited until the sun began to shine. After several hours he looked under the pieces of cloth and saw that the snow under the black cloth melted(融化) much faster than the snow under the white cloth. This proved to him that the black cloth held the heat better than the white cloth.
Soon after this, people began to wear white hats and white clothes during the summer because they were cooler.
Judge the following statements True (T) or False (F)Benjamin Franklin was only a scientist.
One day a friend of his told him something about the relation(关系) between colour and heat.
Something black in colour holds heat better than something white in colour.
This story happened in summer.

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(媒质), if the wavelength islong, the scattering will be short. If the wavelength is short, then 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 light travels far. In fact, it travels farther on rainy days.
Using the red light can help drivers in farther areas sec the lights. It helps drivers stow down or stop in lime. 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.
