In Eq. 38-25 keep both terms, putting A B c0. The equation then describes the superposition of two matter waves of equal amplitude, traveling in opposite directions. (Recall that this is the condition for a standing wave.) (a) Show that |(x, t)|2 is then given by |(x, t)|2 2 02[1 cos 2kx].k(b). Plot this function, and demonstrate that it describes the square of the amplitude of a standing matter wave. (c) Show that the nodes of this standing wave are located at x (2n 1)14 , where n 0, 1, 2, 3, . . . |and l is the de Broglie wavelength of the particle. (d) Write a similar expression for the most probable locations of the particle.

Torque - Torque, ꚍ, is the tendency of a force to rotate an object about some axis. - There is no unique value of the torque on an object. - Its value depends on the choice of a rotational axis - Torque increases with both the force and the distance - ꚍ = rF - ꚍ = r (F sin θ) - SI unit: Nm - Only the tangential component of force causes a torque...
