If matter has a wave nature, why is this wave-like characteristic not observable in our daily experiences? Any object of macroscopic size—including a grain of dust—has an undetectably small wavelength, so any diffraction effects it might exhibit are very small, effectively undetectable. Recall historically how the diffraction of sound waves was at one time well known, but the diffraction of light was not. Only objects of macroscopic size, like an ocean wave, actually exhibit a wave nature. Smaller, microscopic objects—including...

An electron has a de Broglie wavelength of 235 nm .What is the speed of the electron? --------------------------------------------------------------------- How much energy is contained in 1 mol of γ-ray photons with a wavelength of 2.43×10−5 nm . ? ------------------------------------------------------------------------ In a technique used for surface analysis called auger electron spectroscopy (AES), electrons are accelerated toward a metal surface. These electrons cause the emissions of secondary electrons-called auger electrons-from the metal surface. The kinetic energy of the auger electrons depends on the...

The Schrodinger equation is effectively the classical wave equation recast to account for matter waves by using the deBroglie relation. The simplest possible application of the Schrodinger equation is the so-called free particle system where potential energy, V(x)=0. a) Show that plane waves, such as , are solutions (k is the wavevector). b) Use your solution above to find the energy of a free particle. c) What values are possible for position, x, and momentum, p.
