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 Maid of the Mist is a boat tour of Niagara Falls, starting and ending on the American side, crossing briefly into Ontario during a portion of the trip. The boat starts off at a calm part of the Niagara River, near the Rainbow Bridge, and takes its passengers past the American and Bridal Veil Falls, then into the dense mist of spray inside the curve of the Horseshoe Falls, also known as the Canadian Falls. The tour starts and returns on the U.S. side of the river.
