On this site, you are getting the 2nd Year Physics Chapter 20 MCQs with Answer Atomic Spectra. In this chapter, the wavelengths and intensities of electromagnetic radiation are discussed. There are different postulates of Hydrogen that are described by Bohr. De-Broglie interpreted Bohr\u2019s orbits. Then there is the concept of the excitation and ionization potentials. There is uncertainty regarding the position of electrons in the atom. There are X-rays and their production, properties, and uses are very important. One of the most important concepts is the Laser Principle. There are several applications of laser including holography that are very useful. Now check the important MCQs of this chapter given below that are important for the Entrance test preparation.<\/p>\n
