Waves in a Ripple Tank

Generating Waves in a Ripple Tank	The apparatus used for ripple tank movies is described.
Circular Waves: The Relationship between Frequency and Wavelength	The relationship between frequency and wavelength of circular waves in a ripple tank is examined.
Linear Waves: The Relationship between Frequency and Wavelength	The relationship between frequency and wavelength of linear waves in a ripple tank is examined.
Interference of Waves from Two Point Sources	Circular and linear waves in a ripple tank are shown and described.
Relationship of Wave Frequency and Interference Patterns	The number of nodal regions in an interference pattern depends on wave frequency.

Circular and linear waves in a ripple tank are shown and described, and waves from two point sources are used to introduce interference phenomena.
