Why is the wave nature of matter not more apparent to our daily observations?
The de-Broglie wavelength associated with a body of mass m, moving with velocity v is given by
λ = h/ mv. Since, the mass of the objects used in our daily life is very large, hence the de-Broglie wavelength associated with them is quite small and is not visible. Hence, the wave nature of matter is not more apparent to our daily observations
