Bohr Model: Orbits, Speed & Angular Momentum

When an electron orbiting in hydrogen atom in its ground state jumps to higher excited state, the de- Broglie wavelength associated with it

Show answer and solution

Answer: (d)

$\lambda = \frac{h}{mv}$ and $v \propto \frac{1}{n}$ , so $\lambda \propto n$ .
Moving to a higher $n$ lowers the speed, so $\lambda$ grows.
So the answer is (d) will increase.
