Q. In He+ion sample, electrons make transition from fifth excited state to second state only, all different types of photons are observed. Then change in angular momentum of electrons producing the third highest energy photon is how much times of angular momentum of electron in the first orbit.

3rd highest line is 4→2 Hence, change in angular momentum is 2 times of 2πh​.

$3 r d$ highest line is $4 \to 2$
Hence, change in angular momentum is $2$ times of $\frac{h}{2 π}$ .
