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 a grain of dust—do not exhibit a wave nature.    

Only objects of microscopic size, like an atom, actually exhibit a wave nature. Larger, macroscopic objects—including a grain of dust—do not exhibit a wave nature.

Any object of macroscopic size—including a grain of dust—has a large wavelength, so any diffraction effects it might exhibit are very large, too large to be detectable. Recall historically how the diffraction of sound waves was at one time well known, but the diffraction of light was not.

Solutions

Expert Solution

The matter wave is associated with the particles. We observe diffraction only if the wavelength of wave is order of the obstacles or hole. The waves in ocean are not matter waves, they produced due to motion of it's particals about its mean position. The sound waves are actually pressure wave.

i. Why does Darwin believe that nature has put such a premium upon the enhanced survival skills of certain creatures? ii. Darwin compares natural selection to a country undergoing some form of climate change. How does he say that such an example and climate change are similar? iii. Darwin argues that the hand of "natural selection is daily and hourly scrutinising, throughout the world, the slightest variations; rejecting those that are bad, preserving and adding up all that are good;...

Ever wonder why a survey of the American population often has what seems like a very small sample size? 2000 people can tell us what the American population is thinking about. We have formulas to calculate an appropriate sample size for both estimation of the mean and estimation of the proportion. How do they work and why do we need so few to tell us what so many might be thinking?
