If matter has a wave nature, why is this wave-likecharacteristic not observable in our daily experiences?
Any object of macroscopic size—including a grain of dust—has anundetectably small wavelength, so any diffraction effects it mightexhibit are very small, effectively undetectable. Recallhistorically how the diffraction of sound waves was at one timewell known, but the diffraction of light was not.
Only objects of macroscopic size, like an ocean wave, actuallyexhibit a wave nature. Smaller, microscopic objects—including agrain of dust—do not exhibit a wavenature.   Â
Only objects of microscopic size, like an atom, actually exhibita wave nature. Larger, macroscopic objects—including a grain ofdust—do not exhibit a wave nature.
Any object of macroscopic size—including a grain of dust—has alarge wavelength, so any diffraction effects it might exhibit arevery large, too large to be detectable. Recall historically how thediffraction of sound waves was at one time well known, but thediffraction of light was not.
