To determine

To Explain: Wave nature of everyday object is not obvious if one can calculate wavelength of any moving particle from de Broglie’s theory.

Explanation of Solution

Introduction:

de Broglie wavelength can be obtained by:

  $\lambda =\frac{h}{mv}$

Here, h is the Planck’s constant, m is the mass and v is the velocity.

Wave behavior of macroscopic objects is not visible because macroscopic objects have much larger mass than microscopic objects.

The de Broglie wavelength is contrariwise related to the mass of the body. As the mass of the everyday objects is large, the de Broglie wavelength is so small that its wave nature is not observable.

Conclusion:

Hence, wave nature of everyday object is not obvious.
