- Lake of the Woods (French: Lac des Bois; Ojibwe: Pikwedina Sagainan, lit. ‘“inland lake of the sand hills”’) is a lake occupying parts of the Canadian provinces of Ontario and Manitoba and the U.S. state of Minnesota. Lake of the Woods is over 70 miles (110 km) long and wide, containing more than 14,552 islands and 65,000 miles (105,000 km) of shoreline. It is fed by the Rainy River, Shoal Lake, Kakagi Lake and other smaller rivers. The lake drains into the Winnipeg River and then into Lake Winnipeg. Ultimately, its outflow goes north through the Nelson River to Hudson Bay.
- Light (Wikipedia)
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz. The visible band sits adjacent to the infrared (with longer wavelengths and lower frequencies) and the ultraviolet (with shorter wavelengths and higher frequencies), called collectively optical radiation.
