Louis de Broglie proposed that all forms of matter have both wave properties and particle properties. Which of the following explains why diffraction effects are observable only for small-scale objects? A. Wavelengths of large-scale objects are much smaller than any aperture through which the objects could pass. B. Wavelengths of large-scale objects are much larger than any aperture through which the objects could pass. C. Large-scale objects have too much energy to allow observation of their wave properties. D. Large-scale objects move too slowly to allow observation of their wave properties.
