You are trying to identify some elements by using Moseley approach i.e. by observing their characteristic X-ray spectrum. Upon experience, you understood that your setup and the elements you are interested gives only one characteristic X-ray line which are called L series and specifically an Lα line. Derive a Moseley-like expression for Lα lines by using Bohr's assumptions. Choose a suitable element from the Periodic table and calculate the characteristic X-ray emission wave length.

Techniques and applications of quantum theory

Quantum theory, often known as quantum physics, is the foundation of modern physics and encompasses the nature and behavior of matter and energy at the atomic and molecular levels. As the exact nature and behavior of atomic and subatomic particles are impossible to determine, the laws of classical physics do not apply to this discipline. As a result, quantum field theory is primarily based on assumptions and probabilities.
