If the velocity of the electron in Bohr’s first orbit is 2.19×106 ms-1, calculate the de Broglie wavelength associated with it.





Q.59:- If the velocity of the electron in Bohr’s first orbit is 2.19×106 ms-1, calculate the de Broglie wavelength associated with it.

 

 

Answer:-
λ = h/mv = 6.626×10-34 kgm2s-1/(9.11×10-31 kg) (2.19×106 ms-1) = 3.32×10-10 m =332 pm
