Understanding the meaning of a de Broglie wavelength Very small objects exhibit both particle and wave properties, and we need quantum mechanics to describe their behavior. We can use the more familiar classical mechanics to describe larger, everyday objects, which may exhibit particle or wave properties --but not both The key to knowing whether you need quantum mechanics to describe an object is its de Broglie

Unformatted text preview: wavelength. It's given by the formula: Where h is the Planck constant, p is momentum (m*v) When the de Broglie wavelength of an object is equal to or larger than its size, you need quantum mechanics to describe it. Otherwise you can use classical mechanics...
