OBJECTIVES

  • To understand the concept of diffraction of light.
  • To measure and analyze the emission spectral lines of different elements.

PRINCIPLE

The source of electromagnetic radiation is atoms. When the atoms of an element are in an excited state, they return to a lower energy state by emitting electromagnetic (EM) radiation. The transition of the electrons in the atom from a higher energy level to lower unique energy levels for the occupation of electrons, due to this the EM spectrum emitted is a unique signature of an element or a substance. The study of the characteristics of EM radiation emitted by atoms is called Atomic Emission Spectroscopy.

KEY FEATURES

  • Precise Optical Alignment: The optical alignment of the components is attained by the optical bench, the set-up time is faster and experimentation is easy.
  • Rotating table with On-board Telescope: The telescope on the rotating table is mounted with bearings for smooth rotation. The diffraction grating mounted is mounted at the center of the rotating table. The telescope is easy to focus on and operate. The angle of the rotating arm has a least count of 0.1° for accurate measurement of the spectral lines.
  • Power Supply Built in the Discharge Tube Holder: The built-in power supply makes a more compact system with easier changing of the discharge tubes. Easy power connection and no unnecessary wire intrusions
