2. Variational Principle. The energy of a system with wave function ψ is given by where H is the energy operator. The variational principle is a method by which we guess a trial form for the wave function φ, with adjustable parameters, and minimize the resulting energy with respect to the adjustable parameters. This essentially chooses a "best fit" wave...

A water wave traveling in a straight line on a lake is described by the equation y(x,t)=(2.75cm)cos(0.410rad/cmx+6.20rad/st) where y is the displacement perpendicular to the undisturbed surface of the lake. Part A How much time does it take for one complete wave pattern to go past a fisherman in a boat at anchor? Express your answer with the appropriate units....

Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram...

An electron is accelerated through a potential difference of 2.2 kV and directed into a region between two parallel plates separated by 20 mm with a potential difference of120 V between them. The electron is moving perpendicular to the electric field when it enters the region between the plates. What magnetic field is necessary perpendicular to both the electron path...
