Why does the world's most bizarre transnational waterfall emit colorful light at night?

There are many naturally formed wonders in this world, among which waterfalls are one of them. There are many waterfalls in the world, and in our country there are very famous Huangguoshu Waterfall and Hukou Waterfall. There is a waterfall at the junction of the Canadian province of Ontario and the American state of New York. This waterfall is called Niagara Falls. It is one of the three major transnational waterfalls in the world, and it is the largest of them. Niagara Falls is mainly located in Canada and is known as "Thor's Water". At night, this waterfall emits colorful light due to the light emitted by the giant spotlights, which is very beautiful.

This waterfall is very famous in the world. It attracts countless tourists to travel and take photos here every year. It has been developed into a tourist attraction. The water speed and flow of Niagara Falls are very large. The water speed can reach more than 35 kilometers, and the water flow can reach between 1,500 cubic meters and 3,000 cubic meters per second. Because a hydropower station was built upstream of Gai Falls, which blocked the flow of water, the water speed dropped a lot. Before the construction of hydropower stations, the maximum water flow could reach 6,000 cubic meters per second.

Niagara Falls is composed of three parts: Horseshoe Falls, American Falls, and Bridal Veil Falls. Among them, the best viewing area of ??Niagara Falls is the Horseshoe-shaped Falls in Canada. When traveling here, you can not only quietly appreciate the majesty and turbulence of the waterfall on the shore, but you can also take a special beam boat, the Maid of the Mist, to the waterfall to experience the power of the waterfall up close.

Niagara Falls has different scenes during the day and at night. During the day, we can truly feel the majesty of the waterfall, and we can often see rainbows when the sun is shining, which is very beautiful. But at night, Niagara Falls becomes dim, but fortunately, many giant spotlights are installed here, which makes the entire waterfall still glow with charm at night.
