u})$ is $cm^{-1}$ or $m^{-1}$. Rydberg's constant $(R_H)$ also has the same units ($cm^{-1}$ or $m^{-1}$),

Vedclass · Accepted Answer

Rydberg's constant and wave number have same units.

Vedclass · Answer

(NONE) The unit of wave number $(\bar{
u})$ is $cm^{-1}$ or $m^{-1}$. Rydberg's constant $(R_H)$ also has the same units ($cm^{-1}$ or $m^{-1}$),so statement $A$ is correct.
The Lyman series corresponds to transitions to the $n=1$ energy level,which falls in the ultraviolet region,so statement $B$ is correct.
The angular momentum of an electron in an orbit is given by $mvr = \frac{nh}{2 \pi}$. For the ground state,$n=1$,so the angular momentum is $\frac{h}{2 \pi}$,so statement $C$ is correct.
The radius of the first Bohr orbit is $a_0 = 0.529 \ \mathring{A} = 0.529 	imes 10^{-8} \ cm$. This is also correct.
Since all statements are factually correct based on standard atomic theory,there is no incorrect statement among the given options.

Which one of the following statements is not correct?
