When electron jumps from $n = 4$ level to $n = 1$ level, the angular momentum changes by

Options:

Answer:

Solution:

From Bohr's assumption, the angular momentum of $n^{t h}$ level

$m v r = \frac{n h}{2 π}$

The angular momentum of $n = 4$ level

$m v r_{4} = 4 \times \frac{h}{2 π}$

The angular momentum of $n = 1$ level

$m v r_{1} = 1 \times \frac{h}{2 π}$

Change in angular momentum.

$Δ m v r = \frac{4 h}{2 π} - \frac{h}{2 π} = \frac{3 h}{2 π}$
