The characteristic wavelength of a traveling particle varies inversely with the mass of the particle. Calculate the de Broglie wavelength of a particle having the mass of an everyday object, mass = 9.00 g, traveling at ordinary speed 1.00 cm s-1. How would this computed ? compare with the dimensions of a typical atom? (-1 if much smaller, 0 if about the same magnitude, +1 if much bigger)
What does this comparison tell you about the meaningfulness of the wavelike properties of an ordinary object?
A gas is confined to a container with a massless piston at the top.A massless wire is attached to the piston. When an external pressure of 2.00 rm atm is applied to the wire, the gas compresses from 5.90 to 2.95 L. When the external pressure is in..
