Question

Why macroscopic objects in our daily life
do not show wave properties?​

Answer 1

Answer:

Explanation:

matter waves for macroscopic bodies have very small wavelenghts. Accoding to Debroglie's equation , wavelength is inversely proportional to mass of the object.As macroscopic bodies have large mass when compared to micro objects,they cannot exhibit wave property.

Answer 2

Answer:

The macroscopic objects in our daily life do possess the wave properties but the corresponding wavelengths are very small to detect them.

Explanation:

• According to the Louis de-Broglie hypothesis, when we consider any moving particle or object, it will possess both the particle and wave properties.
• The waves associated with macroscopic particles can be called de-Broglie waves or matter waves.
• Louis de-Broglie equation measures the wavelength of the moving particles, which is denoted as -

        $\lambda =\frac{h}{mv}$

       where,

                    λ  = wavelength

                    h  = Plank's constant

                    m = mass

                    v  = velocity

• As momentum of the object ( mass × velocity ) increases, wavelength decreases, hence wavelength is inversely proportional to momentum.
• De broglie wavelengths associated with macroscopic particles are very small. Hence we cannot be able to detect the wave-like properties associated with macroscopic particles (experimentally).
• For example, we can compare the wave properties of microscopic particle (electron) and macroscopic particle (ball) considering the de-Broglie equation.Here, electrons will show more de-Broglie wavelength value and the ball will show very less value which will be immeasurable.
