Physics Chapter 20 Atomic Spectra MCQs with Answers 2nd Year

The second last chapter is about Atomic Spectra and we will study Physics Chapter 20 Atomic Spectra MCQs with Answers 2nd Year. Spectrum is the set of frequencies absorbed or emitted by a substance. The Spectrum of Hydrogen is studied here and it has 5 series. In addition to Rutherford’s atomic model, Bohr proposed an atomic model to remove the objections. His atomic model is a mixture of classical and modern physics. Here we will also study the energies and potentials of these spectra. Then the characteristics of X-rays are very important. There is some uncertainty within the atom-like an electron can’t exist in the nucleus. In the end, there is an important topic of LASER. It has different characteristics and Properties included in this chapter. So, this is a brief intro about the 2nd Year Physics Chapter 20 Atomic Spectra.
