Make use of the free Bohr's Model Calculator to get the frequency of the electromagnetic wave that is emitted or absorbed at the transition of an electron in an atom. It takes the initial and final energy levels of the electron and generates the frequency as output in a less amount of time.
Bohrs Model Calculator: Do you want to determine the frequency of electromagnetic waves? If so, you can take the help of our flexible Bohr's Model Calculator. It gives the exact result along with a detailed explanation to solve it. We have also covered the Bohr model definition, formula, four principles of it and solved example questions.
These are the manual steps to compute the electromagnetic waves frequency using the Bohr's model. Follow these guiding principles to get the output.
Bohr's model defines the atom as a small and positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus similar in structure to the solar system. It was proposed by Neil Bohr in 1915. The four important principles of the Bohr model is along the lines:
The relationship between frequency and energy in the Bohr model gives the frequency of emitted or absorbed by the electron. Bohr model equation is here
ΔE = E2 - E1 = h x f
E1 is the initial energy level of the electron
E2 is the final energy level of the electron
ΔE is the difference of those energies
f is the frequency of the absorbed or emitted electromagnetic wave
h is the Planck's constant and its value is 6.6261 x 10-34 Js.
Question: In an atom, the initial energy level of the electron is 15 eV and final energy level is 24 eV. Find the frequency of the electromagnetic wave?
Initial energy level E1 = 15 eV
final energy level E2 = 24 eV
Bohr's model equation is E2 - E1 = h x f
f = (E2 - E1)/h
f = (24 - 15)/6.6261 x 10-34
= 1.358 x 10-34
Therefore, the frequency is 1.358 x 10-34 THz.

1. How to calculate the frequency of electromagnetic waves using Bohr's model?
The simple steps to find Bohr's model frequency are to get the energy difference of the electrons and divide it by Planck's constant.
2. What are the limitations of Bohr's model of an atom?
The limitations of Bohr's model area are as follows:
3. What are the 4 principles of Bohr's model?
The four important principles of the Bohr model are electrons occupy only certain orbits around the nucleus. Those orbits are called stationary orbits. Energy is emitted when the electron jumps from higher to lower orders and absorbed when jumps from a lower orbit to the higher. Every orbit has an energy associated with it. The amount of energy absorbed or emitted can be calculated using the orbital energies difference.
4. How to find Bohr's radius?
The simple formula to calculate the Bohr's radius is r = (4πϵ0. n2ħ2)/(mze2). Solve the equation after substituting the values in the formula.
