Why Is It That Sound Waves Are Not Normally Considered As Having Particle-like Properties, Nor Raindrops As Having Wave-like Properties? |
|
Answer» The wavelength of a wave is related to its momentum and the PLANCK constant by the EQUATION l=h/mv. For sound waves, their wavelength is too long HENCE the sound particles have too little momentum to exhibit particulate properties. For raindrops, due to their large mass and hence momentum, their wavelength is too SHORT for them to undergo SIGNIFICANT diffraction. Diffraction can only be observable if the dimension of the aperture is comparable to the wavelength of the wave.
