(a) Determine the wavelength of each object, as well as the momentum of each object. (b) Assume that the error in the position of each object is its wavelength. What are the uncertainties in the momentum? Be sure to pay attention to UNITS! U Problem #2: Laser light is normally monochromatic. However, when pulse times become sufficiently short, the energy range can broaden to cover the entire range of visible light (and a laser beam becomes white). Below what pulse time will this phenomenon occur? U Problem #3: The potential energy of a classical harmonic oscillator is given as 2 2 2 1 ) ( x m x V o . We get the quantum harmonic oscillator by putting the above potential function into the time independent Schrodingers equation (1...
