In the Davisson-Germer experiment,the deflection of the galvanometer is proportional to which quantity?

State Heisenberg's uncertainty principle.

The Davisson and Germer experiment proved:

Explain the method of the Davisson and Germer experiment and its results.

Assuming an electron is confined to a $1 \, nm$ wide region,find the uncertainty in momentum using Heisenberg's uncertainty principle. You can assume the uncertainty in position $\Delta x = 1 \, nm$. Assuming $\Delta p = p$,find the energy of the electron in electron volts $(eV)$.

Consider two separate ideal gases of electrons and protons having the same number of particles. The temperature of both gases is the same. The ratio of the uncertainty in determining the position of an electron to that of a proton is proportional to :-
