The de-Brogilc wavelength of an electron in the first Bohr orbit is

equal to one-fourth the circumference of the first orbit

equal to half the circumference of first orbit

equal to twice the circumference of first orbit

equal to the circumference of the first orbit

`-(n^2 h^2)/(4pi^2 mZe^2)`

`-(2pi^2 Z^2 me^4)/(n^2 h^2)`

`-(2pi Ze^2)/(nh)`

`-(n^2 h^2)/(2pi^2 Z^2 me^4)`

`-(n^(2)h^(2))/(4pi^(2)mZe^(2))`

`-(2pi^(2)Z^(2)me^(4))/(n^(2)h^(2))`

`-(2piZe^(2))/(nh)`

`-(n^(2)h^(2))/(2pi^(2)Z^(2)me^(4))`
