The maximum mass of an object traveling at 479 mā sā1 for which the de broglie wavelength is observable, is 3.82Ć10ā»Ā²ā· kg.
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 mā sā1.
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 mā sā1 for which the de broglie wavelength is observable, is 3.82Ć10ā»Ā²ā· kg.
