Matter Waves: de Broglie Wavelength

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

Show answer and solution

Answer: (d)

$\lambda \propto n$ in a Bohr orbit.
Ground state $n=1$ to third excited state $n=4$ : $\lambda$ becomes $4$ times.
So the answer is (d) will increase.
