Document Summary

* louis de broglie proposed that, just as light can have particle-like properties, matter can have wave-like properties. * any particle that has a velocity can also be considered to have a wavelength. * the wavelengths of relatively large objects (such as a moving tennis ball) are much too small, relative to the object"s size, to be noticed. * the wavelengths of very small particles (such as electrons) can have a larger effect on the behaviour of the particle. * de broglie created an equation to calculate the wavelength of any moving object using its mass(m) and velocity(v): * george paget thomson performed an experiment which supported de broglie"s ideas by showing that electrons can be diffracted, similar to waves. * electrons were passed through an extremely thin gold foil onto a photographic plate. * a diffraction appeared on the plate, similar to diffraction patterns created by light and other waves.
