The velocity of electron in a certain Bohr orbit of H bears the ratio `1: 275 ` to the velocity of light M
a. What is the quantum number (n) of orbit ?
b. Calculate the wavelength of the radiation emitted whemn the electron jumps from `(n + 1)` state to the ground state `(R = 1.0987 xx 10^(5) cm^(-1))`
