Solutions

Expert Solution

(iv) If we compare the mass of the person and commercial plane with the mass of electron we get to know that their mass is very much greater than the mass of electron. Also, the wavelength of the person and commercial plane is very less than the wavelength of electron. So, we are unable to observe their quantum properties.
