Question

The angular momentum of an electron in the Bohr's Orbit of hydrogen atom is 4.22 X 10^ -34. Calculate the wavelength of the spectral line when the electron falls from this level to the next lower level. Identify a) the series of spectral line corresponding to this transition, b) spectral region in which the transition takes place... This is really hard one .

Answer 1

I've found out the shell in the above pic. I think the rest of the question is pretty Straightforward.

Answer 2

Answer:

Explanation:

Use mvr=nh÷2π

N find n ..rest is simple
