In physics, the wavelength of a sinusoidal wave is the spatial period of the waveâthe distance over which the wave's shape repeats, and the inverse of the spatial frequency.
The original âCave of the Windsâ was a cavern located behind the Bridal Veil Falls. The Bridal Veil Falls is the smaller waterfall located between Luna Island and Goat Island, beside the American Falls. The Cave of the Winds was an overhanging ledge, consisting of Lockport Dolostone rock, at the top portion of the gorge where the waters of the Bridal Veil Falls flowed over. Originally this portion projected more than 30.5 metres. Due to this overhang of rock, a cavern behind the cascading water was formed.
The water falls at 32 feet per second over the Falls, hitting the base of the Falls with 280 tons of force at the American and Bridal Veil Falls and 2,509 tons of force at the Horseshoe Falls. Niagara Falls is capable of producing over 4 million kilowatts of electricity, which is shared by the United States and Canada. Four of the five Great Lakes drain into the Niagara River, (Superior, Michigan, Huron and Erie) before emptying into Lake Ontario.
