Question

Which expression gives the angular momentum allowed by Bohr’s second postulate?

Options

• \[L_n=nh,\quad n=1,2,3,\ldots\]

• \[L_n=2\pi nh,\quad n=1,2,3,\ldots\]

• \[L_n=\frac{h}{n},\quad n=1,2,3,\ldots\]

• \[L_n=\frac{nh}{2\pi},\quad n=1,2,3,\ldots\]

Answer 1

The permitted angular momentum values are integral multiples of \[\frac{h}{2\pi}\]. The integer \[n\] takes the values \[1,2,3,\ldots\].
