Answer:

Quantum phenomena are not apparent on the macroscopic scale.

Explanation:

As we know that quantum physics is that theoretical study of physics which incorporates the wave particle duality of matter and radiation.

For microscopic matter like electrons, the wave like properties are apparent and as such we use quantum mechanics to study them.

From the de Broglie relationship, the wavelength of a matter wave associated with a particle with mass #m# and velocity #v# is,

#lamda# #= h/(mv)# where #h# is the Planck's constant.

In the macroscopic scale, where #m# is large, #lamda# becomes so less that it is beyond any physical measurement and the wavelike properties of matter do not show and thus, classical mechanics is just sufficient for understanding the physics of macroscopic scale.
