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. 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 disheveled (头发凌乱的) man appeared in court Thursday on charges of murdering a Chinese

woman whose fight with her attacker was seen on webcam (摄像头) by her boyfriend in China. Police

refused to release any details about the crime or its possible motive.

     The body of York University student Liu Qian, 23, of Beijing, was found Friday in her apartment in

Toronto a few hours after her boyfriend witnessed the attack, police said.

     She was found undressed from the waist down but there were no obvious signs of sexual attack or

trauma (创伤) severe enough to kill her. Police say it may be weeks before the results of an autopsy (尸

体解剖) are known.

     Brian Dickson, 29, stood before the court in a wrinkled white shirt and blue jeans as a charge of

first- degree murder was read out. He did not enter a plea. His case was held over until April 26.

     Dickson was arrested Wednesday. Police only announced his name and his age and asked the media

not to publish any photos of Dickson, saying it could compromise the investigation. Toronto police spokesman Tony Vella declined to respond to the request further.

     Liu's father, Liu Jianhui, who arrived from China after being informed of his daughter's death, thanked

authorities for their quick action.

     "I sincerely thank the people concerned with my daughter's case," he told reporters after the arrest.

"Our daughter was studying very hard."

     Police released no motive or details about Dickson, but one friend described the Toronto man as an

aspiring actor.

     Patricia Tomasi, a friend of Dickson's, told The Associated Press that she acted in a play at a local

theater in Toronto with Dickson in 2007.

     "He doesn't seem like the type but that's what they always say," Tomasi said. "He's tall with boyish

good looks. I don't know much about him except that he wanted to be an actor."

     Dickson attended York University where he studied global politics, but did not earn a degree from

there.

     He later worked for the Atlantic Council of Canada (ACC), where he served as an assistant to the

president Juilie Lindhout. According to his biography on a newsletter from the Atlantic Council of

Canada, Dickson has also been a running instructor and has been involved with Developments in

Literacy, a Pakistani aid organization that raises money for children in Pakistan.

     A statement from the Atlantic Council of Canada on Thursday said it was not council policy to

comment on staff, but it confirmed that Dickson had been an intern(实习生) with the council from

September 29, 2008, until March 27, 2009.

     Liu was chatting with her boyfriend, Meng Xianchao, by webcam at about 1 am. Friday when a man

knocked on the door, police said.

     Meng reported seeing a struggle break out between the two before Liu's webcam was shut off. Meng

contacted other friends in Toronto who in turn called police.

   The victim's father, Liu Jianhui, said his daughter studied at Beijing City University before moving to

Canada, where she met Meng.

     Liu Qian's laptop computer, webcam and mobile phone were taken from the apartment the night of

the attack, police said. Police said the online chat was on a live streaming camera and was not recorded,

though investigators were trying to figure out if there was any way they could recover it.

     York University, whose campus is located near one of Toronto's rougher neighborhoods, is one of

Canada's largest universities with more than 53,000 undergraduate and graduate students. About 3,200

of York's students come from more than 150 foreign countries, the university's website says.
