The maximum mass of an object traveling at 479 m⋅s−1 for which the de broglie wavelength is observable, is 3.82×10⁻²⁷ kg.
What is De Broglie equation?
To find the wavelength of a wave, Broglie given an equation. This equation for wavelength is,
[tex]\lambda=\dfrac{h}{mv}[/tex]
Here, (h) is the planks constant, m is mass and (v) is the velocity.
Assuming that the smallest measurable wavelength in an experiment is 0. 450 fm. The speed of the object is 479 m⋅s−1.
Put the values in the formula,
[tex]\lambda=\dfrac{h}{mv}\\ 0.450\times10^{-15}=\dfrac{6.63\times10^{-34}}{m\times479}\\m=3.07\times10^{-21}\rm \;kg[/tex]
Thus, the maximum mass of an object traveling at 479 m⋅s−1 for which the de broglie wavelength is observable, is 3.82×10⁻²⁷ kg.
