Question

Calculate the number of waves made by electron in the 5th bohr orbit of h atom

Answer 1

Most often, the number of waves is made by the electron and it is user to take in 5th Bohr orbit of hydrogen and taken number of waves should be in electron.

This should be originated with the 5 as no of waves are made up of nth orbit and taken place by species is n itself.

Answer 2

Concept:

The angular momentum of electrons circling around the nucleus is quantized in Bohr's atomic model. He said, "Electrons can only move in orbits where their angular momentum is an integral multiple of h/2."

The radius of the orbit, as well as its energy, are quantized when angular momentum is quantized.

Find:

The number of waves.

Solution:

$mvr=\frac{nh}{2 \pi} \\\\mvr=\frac{5h}{2 \pi} \\\\\frac{h}{mv} = \frac{2 \pi}{5} \\\\\lambda=\frac{2 \pi}{5}$

Hence, the number of waves is $5$.
