Question

For which of the following particles will it be most difficult to experimentally verify the de-Broglie relationship?

Options

• an electron 

• a proton

• an α-particle 

• a dust particle

Answer 1

 a dust particle

Explanation:

As `"m"_"dust particle" ≫ "m"_"subatomic particle"`

As a result, its de-Broglie wavelength is extremely small. As a result, analysing its wave nature is extremely difficult. Second, the motion of dust particles is not linear.
