Question

Determine the de broglie wavelength associated with the electron orbiting in ground state of hdrogen atom

Answer 1

For electron in first excited state i.e. n = 2.

So, if λ be its wavelength (De-Broglie), then we have

n λ = 2πrn

where,rn is the radius of second orbit.

Answer 2

➡Wave length

λ=hmv

=6.63×10−341.67×10−27×103

=0.4nm
